General features transparent gas permeability, and can protect the lipid permeability better acid-resistant, good. Heat resistant & cooling is not suitable for use at temperatures. Normally, it is often used in cosmetic packaging. Fruit juice, vegetable oil Vinegar and water bottles, plastics, chemical products, then the time will be repeatedly applied chemicals that can dissolve. Especially when the bottles are collapsible pet bottles and jars, including opaque white (opaque white bottle will melt more, especially when the store was not how).2. the bottles made of polystyrene, enough lalina.

In General, tablets containing vitamins, spices, and make it larger for use packaging to transport the milk, but not commonly used in our home.3. the bottle is made from ethylene lalina enough. There are two ways to use enough ATM lalina League low density resin and resin lalina Lee at high density. Typically, bottles. This type will allow water vapor permeability, but less will allow gas permeation resistant, medium acidity. heat resistance is not very good, but would be much better withstands. For the bottle with high density type, often used in milk packaging. Drinking water, chemicals, detergents, and cosmetics.4. bottle made from polyethylene lalina raphi lean enough. Generally, properties allow water vapor permeability, but less will allow good permeability, gas, acid-resistant, heat-resistant medium well but will not tolerate the cold, so it is not suitable for freezer. Commonly used in drug packaging Fruit juice Syrup Shampoo and cosmetics.5. bottle made from the winter League-a.t. lalina enough topically enough fi lalina Esther. PET bottles are generally solid, transparent properties. Protection against ingress of water vapour permeability, gas protected medium, but very good.
