Liquiglide drawingLiquiGlide can be engineered to control the speed that the object, liquid or material slide over the surface by changing the materials or structure of the coating.Who hasn’t lamented at those last portions of mayo clinging to the interior of a jar or a Heinz 57 sauce that’s so thick it becomes increasingly difficult to dispense the flavorful condiment as the volume dwindles with use? 

So tantalizingly close, yet frustratingly inaccessible…for now.
Some product waste that has been previously thought of as unavoidable may not be so elusive with LiquiGlide, a technology developed at the Massachusetts Institute of Technology by five students and professor Kripa Varanasi. 

Developed in the Varanasi Research Group at MIT, the coating is made from nontoxic materials and is easily applied to food packaging. 

Industry Intel reported in mid-2012 that MIT’s “LiquiGlide coating is so slippery it allows all condiments to pour from the bottle. When applied to the inside of a bottle, the walls are so lubricated that sauces that would have normally stuck to the insides almost fall out. 

“The team estimates, that with this innovation, they would be able to make a dent on the estimated 1 million pounds of global food waste thrown out each year. In addition, they would eliminate the need for large squeeze-bottle caps, saving about 25,000 tons of petroleum-based plastics annually. 

According to MIT PhD candidate Dave Smith, LiquiGlide is almost like a structured liquid, because it is both rigid like a solid, yet lubricated like a liquid.” 

A composite of solid and liquid

What is LiquiGlide? Here’s the official description: “Liquid-impregnated surfaces are a patent-pending, super-slippery surface technology that comprise a composite of solid and liquid materials, where the solid holds the liquid tightly at the surface and the liquid provides the lubricity.”

Reportedly the initial application was aimed at coating car windshields, but it works equally well on many surfaces from airplane wings to containers made of glass, plastic, metal and ceramic, which covers a lot of ground in packaging for foods and other products.

The LiquiGlide website also offers this: “Application-specific custom formulations of the coating are created, so for food packaging, the coating is made from FDA-approved, edible materials.”

Interestingly, the coating can be engineered to control the speed that the object, liquid or material slide over the surface by changing the materials or structure of the coating. Thus, LiquiGlide can be tailored for the container type as well as for the product the customer wants to have slide more easily out of the container. 

It is so uniquely utilitarian that LiquiGlide has deservedly garnered a case load of high-profile accolades, including in late 2012 when it was recognized by Time magazine as one (of 26) of the Best inventions of 2012. Forbes also named it one of the best food inventions of 2012.

We reached out to the MIT LiquiGlide contacts a number of times by phone and email, but were unable to gain feedback for an update at press time. 

However, we did uncover a technical paper published in February 2013 in the technical publication Soft Matter (2013, 9, 1772) from RSC Publishing entitled “Droplet mobility on lubricant-impregnated surfaces,” which credits half of the same team members cited in the LiquiGlide literature including lead Varanasi. 

In the introduction, it provides background on a method-and the difficulty-of entrapping air pockets in a structured surface to enhance the sliding properties of materials. The paper offers a solution that involves “surfaces containing pockets of a lubricating liquid rather than of air. Stabilized by the capillary forces arising from the microscopic texture, the lubricant lets the droplet above it move with remarkable ease.” It also is stated that such non-wetting surfaces can provide self-cleaning properties.

These details simply underscore the fact that LiquiGlide is a slick development.

Apart from consumers’ ongoing frustration at not getting those last dabs of condiments from containers, the buzz for this out-of-the-box (bottle?) development could not have come at a more opportune time when the food industry is taking an ever closer look to reducing waste. 

At year’s end, one national consumer research organization, the Values Institute at DGWB singled out Food Waste Consciousness as one of its top five health trends predicted for 2013. 

Deep in the supply chain

And just last month, a new global campaign to cut food waste was launched by the U.N. Environment Programme (UNEP), the Food and Agriculture Organization (FAO) and partners: The Think.Eat.Save. Reduce Your Foodprint campaign, which is in support of the SAVE FOOD Initiative to reduce food loss and waste along the entire chain of food production and consumption. 

It’s at that last portion of the supply chain where the value-add of processing, packaging and transportation magnifies the cost of waste versus losses farther upstream, opening up food for thought for an option like LiquiGlide.

If this wonder coating has a sticking point, it may be cost: According to Time, the estimated cost per container for LiquiGlide is 25 cents, which puts it out of the reach of most packaged foods. 

However, as development continues across the many platforms it is applicable for, including non-packaging, costs will likely become more reasonable if not practical. It is conceivable this technology may be sliding into our futures faster than we think.

Information About Plastic Injection Molding

Information About Plastic Injection Molding

Plastic is the most versatile material that is used in most applications today. The wide range used of this material has made a great impact in most industrial world. One of the processes in creating plastic product today is called plastic injection molding. This is a process of manufacturing plastic by using thermosetting plastic and thermoplastic substance.

The first plastic product called Parkensine was created by Alexander Parkes in 1851. This product is can be molded, heated and usually retains it shape when it is cooled, thus the downside of this is, it is extremely flammable, expensive and easy to crack. Another invention of plastic called celluloid was developed by john Wesley Hyatt. This product was an improved version of Parkes’s invention. It is through John Wesley Hyatt and his brother wherein the first molding injection machine was developed. This machine is a simpler version of today’s injection molding machine.

Plastic injection molding is commonly used for creating various parts of cars, from tiniest elements to the whole body components. This process involves feeding of material into barrel that is heated, afterwards, the material was mixed then placed into a cavity where it is allowed to harden and cooled. The product was design mostly by an engineer or an industrial engineer. After the molded product was harden and cooled, a machine called precision-machined, with the supervision of a mold-maker, is used to form the specific feature of a part of a specified product.

Aside from creating various components of a car, injection molding is also used for almost plastic goods such as bottle caps, wire pools, packaging, pocket combs and some gadget components. This process is widely used way in developing parts. It is used to produce vast amount of parts.

The common advantages of this process are low labor cost, scrap losses are minimized, vast rate of production, finishing of parts is minimized and wide range of materials are can be utilized.

Watch Plastic Planet Movie 2010 Online Stream

However, as Boote learns, the incorruptibility of plastic is largely industry hype. The problem is that there’s no regulation of what goes into plastics, which are routinely combined with toxic additives. So while that beach bucket in the garage might be around another four centuries, part of it is already disintegrating and entering the food chain.

Boote visits a Chinese manufacturer of plastic blow-up globes — a fortuitous metaphor — which turn out to be heavily adulterated with mercury and the toxic compound Bisphenol A. In Italy, he interviews Beatrice Bortolozzo, whose father, Gabriele, was a kind of Karen Silkwood, drawing attention to chemicals being pumped into the Venice lagoon. Interspersed with these and other scenes are sped-up vignettes of families from different social and ethnic groups emptying their homes of a phenomenal number of plastic products.

The docu also addresses the pollution problem, from the now plastic-strewn desert where “Lawrence of Arabia” was shot to the Pacific Ocean, where Charles Moore reveals an enormous patch of water thick with bottle caps and other plastic debris. There is a positive note toward the end, with a discussion of degradable bioplastics, but as Boote points out, even were the world to switch tomorrow, we’d still have billions of tons of the old stuff sitting around for another few centuries.

The docu’s cumulative effect is bound to make auds think about the kinds of plastics they use and how they dispose of them. While the topic is serious, Boote makes it playful through his own humor and Peter Hoehsl’s manga-style animation. Though shot in 15 countries around the globe, the lensing has an attractive cohesiveness. For some inexplicable reason, the narrator in the international-release version maintains Boote’s first-person p.o.v., though it’s obvious the voice does not belong to the helmer.

The World of Plastic Mouldings

The World of Plastic Mouldings

Do you see your electrical outlet’s plastic covering? Ever wondered how these plastic moulds and materials came to be? Well, they did not just appear from out of nowhere, that’s for sure. There are actually different methods and processes involved in creating a plastic mould and we will get to know them one by one.

One of the first things that you need to know is that, technically speaking, plastic moulding is the procedure by which organic materials are turned into non-organic material (plastic) for industrial use. The first plastic was produced in 1851 by Alexander Parks and was known as Parkesine. It was, however, John Wesley Hyatt who was able to create a way by which plastic can be manufactured into its finished form.

Plastic mouldings can be done in a number of different ways, some of which are injection moulding, blow moulding, compression, moulding, gas assist moulding, rotational moulding, and thermoforming.

Injection moulding is the most popular way by which plastics are processed. In this method, injection moulders force melted plastic into a mould cavity. Two types of mould are made us of – an injection mould and an ejector mould. It is through an opening called sprue that the resin enters the cavity. This process is usually utilized in making kitchen utensils and bottle caps, among others.

The next most commonly used plastic mouldings technique is blow moulding, also known as blow forming, a process that is usually employed in creating  hollow plastic parts. Blow forming comes in three forms – extrusion blow moulding, injection blow moulding, and stretch blow moulding. It starts with the formation of the parison or preform and ends with a pressurized gas expanding the preform, pressing it against the mould cavity. Blow forming equipments are usually priced higher than those that are used for injection moulding.

The third most frequently used technique in plastic mouldings is the compression moulding. In this technique, a pre-heated moulding material is placed in an open, heated mould cavity.  The mould is then closed with a plug member and then pressure is applied. This technique is usually makes use of vertical presses and is the preferred method in processing automotive parts as well as ultra-large basic shape productions. It is also considered to be one of the cheapest moulding techniques.

Medical Plastic Injection Moulding ? Procedure and Products

Medical Plastic Injection Moulding ? Procedure and Products

In 1868, John Wesley Hyatt developed the first plastic injection mold, and the plastic injection moulding process. He used the plunger method to successfully inject hot, liquid celluloid, often called the first thermoplastic, into a split-die mold. This process was little changed until James Hendry built the first screw plastic injection mold in 1946. Today, nearly all industrial and medical plastic injection moulding processes use the screw method.

Plastic moulding is a very methodological and technical process. Thus it needs experts in this type of manufacturing business for it to meet the safety terms and to be competitive in the market. A very scientific and systematic mechanical study is first made before going into this endeavor. Here I have discussed some known plastic injection moulding process that can help you to understand the various ways it is done for industry specific plastic products.

1. Injection Moulding.

Examples of applications: Medical plastic laryngeal mask components, laboratory products, extraction systems, toys, aircraft undercarriage components, kitchen utensils, bottle caps, and cell phone stands.

In Injection Moulding, melted plastic is forced into a mold cavity. Once cooled, the mold can be removed. This plastic injection moulding process is commonly used in mass-production or prototyping of a product. Typically this process is used to produce plastic mouldings where the relatively high tooling cost can be justified by low unit costs and tolerances which cannot be achieved by other moulding processes.

2. Blow Moulding.

Examples of applications: Automotive, Toys, Recreational, tubes and containers, Medical, Housework Appliances

The process is divided into three steps: injection, blowing and ejection. Blow moulding is like plastic injection moulding except that hot liquid plastic pours out of a barrel vertically in a molten tube. The mold closes on it and forces it outward to conform to the inside shape of the mold. When it is cooled, the hollow part is formed. Equipments needed in setting-up a blow moulding business are relatively higher than injection moulding.

3. Compression Moulding.

Examples of applications:  Automotive exterior panels especially for commercial vehicles, Radio & appliance knobs, ash trays & electrical parts.

In this type of plastic moulding, a slug of hard plastic is pressed between two heated mold halves. Compression moulding usually uses vertical presses instead of the horizontal presses used for injection and blow moulding. The parts formed are then air-cooled. Prices of equipments used for compression moulding are moderate.

4. Film Insert Moulding.

Examples of applications: FIM can be used to apply clear scratch-resistant hard coats, logos, text and graphics in any color or combination of colors to plastic parts prior to injection molding.

This plastic moulding technique imbeds an image beneath the surface of a molded part. A material like film or fabric is inserted into a mold. Plastic is then injected.

5. Gas Assist Moulding

Examples of applications:  Flat panels for office equipment, Computer enclosures, Furniture, i.e. tabletops, Automotive panels, Domestic appliances – e.g. fridges.

Also called gas injection moulding is used to create plastic parts with hollow interiors. Partial shot of plastic is then followed by high-pressure gas to fill the mold cavity with plastic.

6. Rotational Moulding.

Examples of applications:  All kinds of plastics mostly hollow Plastic Parts.

Hollow molds packed with powdered plastic are secured to pipe-like spokes that extend from a central hub. The molds rotate on separate axes at once. The hub swings the whole mold to a closed furnace room causing the powder to melt and stick to the insides of the tools. As the molds turn slowly, the tools move into a cooling room. Here, sprayed water causes the plastic to harden into a hollow part. In this type of plastic moulding, tooling costs are low and piece prices are high. Cycle time takes about 40-45 minutes.

7. Structural Foam Moulding.

Examples of applications: Typical products are large trash containers, freeway sand safety containers and in-ground housing for water systems.

Structural foam moulding is a process of plastic injection moulding usually used for parts that require thicker walls than standard injection moulding. Inserting a small amount of nitrogen or chemical blow agent into the plastic material makes the walls thicker. Foaming happens as the melted plastic material enters the mold cavity. A thin plastic skin forms and solidifies in the mold wall. This type of plastic moulding can be used with any thermoplastic that can be injection molded.

8. Thermoforming.

Examples of applications: Clamshells, Trays, Blisters, Displays, Guards, Covers, Totes, Shields, medical plastics

In this plastic moulding process, sheets of pre-extruded rigid plastics are horizontally heated and sucked down into hollow one-piece tools. When the hot plastic solidifies, its shape conforms to that of the mold. Tooling costs are usually low and piece prices vary on the machinery.

Goodbrand Plastics provides Plastic Injection moulding services to diverse sectors with specialisation in Medical plastic injection moulding from our site in Sandbach, Cheshire, northwest England.

Quality Bottle Closures for Homes and Hotels

Quality Bottle Closures for Homes and Hotels

Caps of various sizes and of any make have been in the market since a very long time. Local manufacturers have tripled in number over the last few years. Through the number of factories have increased by leaps and bounds, <a rel=”nofollow” onclick=”javascript:_gaq.push([‘_trackPageview’, ‘/outgoing/article_exit_link’]);” href=”http://www.classiccaps.com”>quality bottle closures</a> are becoming very difficult to procure nowadays. The high cost of manufacturing good caps to meet the demand of the market now poses a big problem. However, in lieu of all this, several methods of production to create different grades of materials to make caps are now prevalent in the market. Plastic bottle cap closures come in a variety of style and colors. These caps come packed in small kits or in bulk packs, if bought from wholesale dealers. Each cap comes with a manufacturing code to signify the production line and the make for the company to keep track of its product inventory. The plastic caps are generally in four major categories: smooth, brush, and dome. The more advanced small plastic bottle closures have additional features like child resistant, tamper proof, tamper evident, etc. Phenolic lined caps tend to be hardier and last longer.


Wine bottle closures are also extremely popular in the market. Their entry is very recent and a lot of studies have gone into their relative effectiveness because preserving wine is very important due to its cost and also to retain its flavor and taste over a longer period of time. Screw caps were in vogue for a very long time in the market till these entered the consumer domain. Cork closures have a very long tradition and their usage on wine bottles now signifies that these wines are inferior and not of an acceptable quality. Generally, there are two main materials that are used to manufacture wine bottle closures. They are made either of metal or cork. Good quality natural cork is high to come by these days. Moreover, cork tens to affect the taste and quality of wine by making it dull and unfit to drink, better defines as the ‘cork taint’ by manufacturers. To address this problem, an alternative of synthetic cork was also considered. But, this kind of cork tends to leave a ‘plastic taint’ that many consumers might find extremely difficult to deal with and find it extremely unsatisfactory.  Keeping all the above factors in mind, we have now seen another solution to the above problem and that is the experimental use of metal in closures. Metal caps can be produced easily in bulk. They are extremely efficient in sealing the wine and keeping it safe for extended periods of time. Most wines are not bought in bulk because most collectors of wine are experienced connoisseurs and each and every bottle added to their shelves are extremely expensive and are a matter of utmost pride to their owners.

Diane Houston has his own packaging industry and is a Quality bottle closures. He writes regularly about the bottle caps and packaging industry.
