Ritz-Carlton Moving to “Green” Bottles

Ritz-Carlton Moving to “Green” Bottles

Ritz Carlton’s U.S. and Caribbean hotels (which account for 40 of the chain’s 73 hotels) will stop offering plastic water bottles and will switch to plant-based, biodegradable material for their hotel branded water bottles.  This move towards using an environmentally much friendlier material for water bottles is thought to be the first among hotel chains.

The new bottles are made totally from plants and being all natural can decompose in 30 days in a commercial composting facility.  Alternatively these “green” bottles can be reprocessed and 100 percent remade into new bottles.  The benefits are many including that making one new bottle uses half the fossil fuels of a traditional plastic water bottle, as well as 45 percent less energy, and generates 75 percent less greenhouse gases. The bottles hold water normally without fear they will decompose in front of you or while in the refrigerator.

Lest anyone think that this is largely an empty gesture, Ritz Carlton distributes five million 16 oz. water bottles per year, according to the Marriott owned brand. The positive environmental implications could increase dramatically if all Marriot hotels follow Ritz Carlton’s lead.

Other chains cannot dismiss switching to environmentally friendly water bottles based on cost concerns, since Marriott has announced that the new bottles will cost the same as the old water bottles. Ultimately, the cost of such bottles will likely be lowered as they become more common. As with many environmental advances, the initial cost is a reason for concern, but once they become the standard, many times the price comes down to equal or even lower than the item they replace.

Bottle raw material market, "Made in China" against monopolies

Bottle raw material market, "Made in China" against monopolies

Drink A small bottle cap, is not so simple. Drink to consumer spending since produced before the seal depends on it, and if caused by untight seal leaks, outside air infiltration advantage of the opportunity, they will mildew in the beverage, which requires both strong and easy to open lid , that has a good balance of rigidity and toughness. Beverage packaging process, there may be through the high temperature and pressure, which requires such a cap can withstand the test without deformation. Cap on the number of beautiful patterns also printed, marked with laser security, promotional signs. All the raw materials required cap should be easy to process.

Steady occupation of the market YPC

As the largest producer of polypropylene, Yangzi Petrochemical full use of equipment with annual production capacity 400,000 tons of polypropylene and related small pilot plant test and the advantage of organizations through a series of research scientists, first in the country family developed by copolymerization polypropylene caps Compound YPJ-706, and in 2005 put into industrial production. The performance tests, the performance of the special materials in full compliance with domestic cap polypropylene product requirements. As the excellent product performance, health and environmental, in addition to high-end bottle production can be used for household appliances such as production of parts and toys.

The product by Jiangsu Province, CDC’s health testing, to the United States Food Drug Administration standards. But to enter the wider market, but also must Coca-Cola Review of the company’s raw material certification system.

2006 in the second half, leading Institute of Yangzi Petrochemical Company led to visit a number of delicious Coke Cap companies and their supporting manufacturers. First half of 2007, Coca-Cola sent a group of experts dedicated to the Yangtze Institute, plastics research, special material on the Yangtze Petrochemical R & D, production scale and supporting facilities such as the ability to do a comprehensive study comprehensive, and special material for cap inspection and certification. In mid-October last year, Coca-Cola bottle cap manufacturer to issue a formal use of special materials for YPC cap certification. With Coca-Cola

certification, Yangzi Petrochemical Compound became famous cap. Each of the Yangtze River Delta market demand for raw material polypropylene cap of 10 million metric tons, most of the foreign share of the original has, Yangzi Petrochemical cap the rise of special materials to break this situation, the present, the company has produced more than 5000 tons, is steadily occupy the market.

Raw material market is not easy to access lid

Plastics are increasingly becoming the raw materials of various caps. However, not all manufacturers of plastic products can be used to make bottle cap. Because there are so many demands caps a long time, almost all the major domestic manufacturers of bottled drinks companies have fixed their production caps and cap is basically a raw material supply of foreign-funded enterprises, joint ventures monopoly. To enter the market cap of raw materials must pass stringent or even close to related businesses harsh review of the raw material certification system.

U.S. Coca-Cola brand known worldwide, their reputation is behind the near-stringent review of the industry chain, so Coca-Cola system has high raw material certification authority. Through this certification system of review, have material supplier to the Coca-Cola bottle qualifications, and this is equivalent to get the Plastic bottles Global Pass covers the industry.

The Torque Value Testing for Bottle Cap/Closure- Lock Force & Open Force

The Torque Value Testing for Bottle Cap/Closure- Lock Force & Open Force

Bottle cap torque force (bottle cap open and lock force) is one of the main factors affecting the sealing performance. Over torque force would bring great difficulties for open and winding up of bottle cup, and thus, reduce the convenience. Insufficient torque force would affect the seal performance of the container, and may further result in the leakage during transportation. Now, package design is designated to bring more convenience for fast consumption, and easy openness of bottle cap is one of the aims. When dealing such testing, ASTM D2063,ASTM D3198, ASTM D3474 are the standard, and craft-proof ring should be cut before testing.

The sealing performance of plastic bottle is the most important factor affecting package leakage and product deterioration. Excellent open easiness and sealing performance can be guaranteed through reasonable control of sealing performance and torque value. The barrier property of plastic bottles, including gas transmission quantity and water vapor transmission quantity, should also be controlled so as to guarantee the product quality during shelf-life period.

How To Build Bottle Rockets and Launch Them Sky-High!

How To Build Bottle Rockets and Launch Them Sky-High!

Find a new use for plastic bottles by making bottle rockets! You know making these types of bottle rockets really add fun to your kids and may be yourself too.

If you have a large collection of plastic bottles, you might have thought of building bottle rockets. Only thing is, you don’t know how to build a bottle rocket. The results can be dramatic and a good way to use up plastic bottles!

You need two 2-liter plastic bottles, a small plastic cone, duct tape, scissors, string, modeling clay, a manila folder with no pockets, a black trash bag and a hole-puncher. If you’re a child or very clumsy, ask an adult to help you.

Cut the top and bottom off one bottle so you’re left with a plastic cylinder. This forms the storage compartment, or fuselage, for the parachute. Tape the fuselage to the bottom of second plastic bottle. Cut 3 triangular fins from the folder and tape them to the second plastic bottle. The fins should be situated nearer to the end with the bottle cap.

Cut the pointed end off the cone to form the nose of your rocket. Stop up the opening with a wad of clay. Attach the rocket nose to the fuselage with the string, attached by tape on the inside of the cone and fuselage. You can cut out 3 mini fins to balance the cone atop of the fuselage if needed.

To make the parachute, cut the closed end off the trash bag. Fold the bag in half lengthwise, making sure the edges are matched. Then, along the long axis, fold it in half. Fold this shape on the diagonal to form a triangle. Trim away the excess.

Upon unfolding the bag, you will now have 2 circles. You will only need one. Fold the circle into 16 parts, marking the creases as you go. Reinforce both sides of the creases near the outer edge of the circle with masking tape and punch holes through the tape. Fold the chute in half again and thread string through the holes. Attach the chute to the fuselage with duct tape. Pack the chute loosely into the fuselage and cap it with the cone.

To launch the rocket, first half-fill it with water. Balance it on its fins or a launching platform; add pressure into the bottle such as with a bicycle pump until your bottle rocket is launched!

How to Improve Opening Easiness of Package

How to Improve Opening Easiness of Package

Abstract: in review of container package and flexible package, this article introduces some important indexes of opening easiness as well as the relating test methods. It also briefs on the importance of these tests.

Keywords: opening easiness, friction coefficient, torque, seal strength, puncture resistance, and tearing strength

 

Opening easiness of package, mainly designed for small packages, is a kind of packaging convenience characteristic offered to consumers. In the past, we focused on how to improve sealing performance and fastness of packages to avoid damage and leakage of the contents; while opening easiness of package was rarely mentioned and the real opening result of the packages was not good. Auxiliary tools like scissors had been often used in package opening, which would often lead to hurt to hands. This not only increased the difficulty of consumption, but also affected overall images of packages. The notion of opening easiness package has come to the market for a short period of time, and is warmly welcomed by customers. Therefore, opening easiness of package has become a tendency of package design.

How to improve opening easiness of package? Could perceptual knowledge of opening easiness be quantified into several testing items? This article will give the following introduction as to container and flexible package.

1   Container

Container package can be divided into bottle form and cup form. Bottle package, such as plastic bottle and glass bottle, is designed to be easily opened (usually by opening bottle cap) by consumers. The needed torque force in bottle cap opening should be controlled .To some caps with special anti-fake function; opening force of pull-tab should also be controlled. Cup package is mainly opened by peeling off the sealing place or by piercing the material of cup rim using tools like suction pipe. Therefore, for different packages, seal strength or puncture resistance of materials needs to be adjusted. For example, package of children’s beverage should be designed according to their grip strength and wrist strength. Generally speaking, the following parameters should be considered to improve opening easiness of package.

1.1 Friction Coefficient Testing

Friction coefficient of package external wall, bottle cap surface or cap material surface should be tested.

Friction coefficient of package external wall is tested to help consumers firmly hold the bottle body, and avoid sipping when opening. Slipping phenomenon during package opening will greatly increase opening difficulties.

Friction coefficient between the bottle cap (spin opening) and its contact area with hand during opening is also very important. Generally speaking, the bigger this coefficient is, the better the result is. The screws on plastic cap is an effective measure to increase friction coefficient

Some cup packages are sealed with cap materials, with the main sealing place at cup rim. A common opening method is to peel off the sealing material at the cup rim. Therefore, friction coefficient of film surface should be increased to avoid slipping during peeling off of cap material.

1.2 Torque Force Test 

For container opened by cap spinning, torque test of bottle cap is necessary. At present, procedure of cap spinning usually fulfilled with automatic cap springing device of production line after filling, during which torque force can be accurately controlled. Torque force of one batch package can be test through random sampling, and the adjustment of this torque force according to the estimated consumption group during design, a better opening effect can be realized.

1.3 Seal Strength Test

Some cup containers without cap are sealed with cap sealing materials, such as fruit jelly cup and yogurt cup. This kind of package quickly becomes popularized for the reason of its low in cost; and on the other hand, it can offer portable packages easy to carry and moderate in quantity. At present, the machine that combines procedures of cup body flushing, content filling, cap material sealing and finished product outputting in one has been introduced. Such machine can avoid the possible cup body pollution after production and before filling of contents. By this way, storage cost of bottle body is also saved. 

The test of seal strength at cup rim is extremely important. On the one hand, sealed place of cup rim will meet impact of external force during storage and transportation with the result of cracks at the sealing places and leakage of contents owing to lower seal strength. Conversely, the seal strength being too great will increase the chances of opening difficulty when peeling off at the seal place (such as cup surface of jelly cup). Therefore, it is preferable that seal strength is controlled within a reasonable scope. Special attention should be made to the difference of cap material, cup body sealing and film sealing, especially the shape of seal head and seal width. That is why professional seal instrument is recommended in testing this item. Specialized Cup Package Seal Instrument introduced by Labthink can be customer-tailored according to the dimension of test specimen. 

1.4 Puncture Resistance Test

Puncture resistance of cap material is needed for packages (such as yoghourt cup) opened by piecing. Different from puncture resistance test of other materials, puncture resistance of the cap material must be controlled within a proper scope: on one hand, it must be able to endure the impact of external force during storage and transportation to avoid cap material fracture; on the other hand, the package should be easily opened with tools like suction pipe.

2   Flexible Package Bag

 Bag packages are various in forms. But it is usually for small packages that have certain requirement on opening easiness. For example, small quantity package of food and medical granules, puffed food and articles of daily use, etc. Bag package is usually opened at the provided easy aperture or at one sealing end of the package.  Of course, auxiliary tools like scissors can also be used. The most ideal situation is that package can be opened conveniently without auxiliary tools; and this can comply with the portable and ready-to-use characteristics of small package to maximum extent. Taking various opening methods of flexible package into consideration, opening easiness can be improved by the following parameters:

2.1 Friction Coefficient

Friction coefficient of package external surface is the main factor for customers to have a film holding in order to avoid slipping phenomenon during package opening.

2.2 Tearing Strength Test

Opening package in the place of easy aperture is the most convenient way, which needs little strength and no auxiliary tools. So easy aperture has got wide applications in the design of flexible package. The measurement of the force needed to open easy aperture can be estimated through testing film tearing strength. Owing to different variation of the tension in vertical and horizontal orientation, this will result in aeolotropy of the produced film to some extent. It is the same case to tearing test. Therefore, based on the tearing strength of material, proper directions of aperture should be selected in the design of package structure so as to increase opening easiness.

2.3 Seal Property Testing

Opening package in the seal place at one end of the package is also a commonly used way. Seal place of flexible package is the main position to endure external force during storage and transportation. Therefore to secure the quality of inner content, seal strength of materials needs to be improved. On the premise that inner content of package is intact, seal strength of seal place should be reduced as much as possible. Of course, the most suitable scope of seal strength is decided by the nature of package material and the inner content, and should be decided through complete testing according to the actual condition.

3 The Necessity of Comprehensive Test  

As to container and flexible package, this article briefs on the main influencing factors of opening easiness. However, in actual application, special attention should be paid to the comprehensive testing of relating parameters. If friction of material surface does not match with the tearing force well, the slipping will result in difficulties of opening; while the great friction will impose influences on filling efficiency of products. Therefore, it is necessary to comprehensively test the relevant opening easiness parameters of the material, and carry out opening stimulation tests under different situations.
