Polyethylene containers concept and interpretation

And such as polyethylene containers good acid, alkaline, but not resistance to many organic solvents, and nylon container hydrocarbon and organic solvent resistance, but poor acid-proof alkaline ( Especially the acidproof performance difference) And so on. Polycarbonate bottles can be used for high temperature filling goods ( Such as fruit juice) Packaging, but if the polycarbonate bottle used for holding need good barrier property of fizzy drinks, To prevent carbon dioxide from the beverage escape) Or cooking oil ( To prevent oxygen into the bottle, lest the cooking oil oxidation and rancidity) , is not well protect the goods, not the ideal packing effect; With ordinary polyester stretch packaging bottle of carbonated drinks, can effectively prevent the beverage of carbon dioxide in the escape, Polyester stretch bottle of blocking high performance) , be used for packaging of edible oil, can delay the oxidation of the cooking oil and prolong the shelf life ( Polyester stretch bottle of oxygen barrier performance is good, can effectively prevent the oxygen from the atmosphere through the wall into the bottle container) , but use it for packing items like high temperature filling juice, when high temperature filling, polyester stretch bottle will happen serious metamorphic lost their use value. Polyethylene bottle can dress materials such as acid and alkali and unfavorable dressed organic solvent such as benzene, toluene ( Polyethylene bottle swelling strength significantly decreased or organic solvents by the container wall escape) And nylon container is unfavorable storage materials such as acid and alkali, but used to dress up organic solvent such as benzene, xylene is very appropriate.
