PE, PVC, pp, pet plastic bottle is now more commonly used plastic material, the four kinds of plastic material has what characteristics, their respective along and see it.
PE is one of the world's largest synthetic resin production, is one of the biggest plastic packaging materials of consumption, but low rigidity, PE plastic used in plastic packaging has certain restrictions.
PP plastic is isotactic crystallization, thermal stability is better, but more brittle material, easy broken, mainly polypropylene material.
Microwave oven boxes made with this material, resistant to high temperature of 130 ℃, transparency is poor, this is the only plastic box can be put into the microwave, reusable after careful cleaning.
Is PVC and called PVC, PVC resin, often making project profiles and plastic products, daily life common raincoat, building materials, plastic film, plastic boxes, etc.
Plasticity is good, the price is cheap.
But only can withstand temperatures up to 81 ℃.
This kind of material of plastic products are prone to toxic and harmful substances, at present, this kind of material has been less used in packing food container.
Don't let it is heated.
PET not only in the blow molding of bottle showed excellent tensile properties, but also for the pressure produced carbonated drinks also have good performance.
Not only that, PET carbamate resistance is much higher than PVC, PC, PE and PP, can effectively prevent the evaporation of the water vapor.
PET plasticizing temperature - in 243
270 ℃, PET also has good heat resistance, thermal oxidation resistance, good gloss, and optical properties, the proportion of small, low content of acetaldehyde and the price is reasonable, etc.
As PET processing technology of rapid improvement of the plasticity of the molding advantages make it occupy the position of the main packaging market.
PET plastic bottles is widely used in blow molding manufacturing bottle hollow container, such as lemon juice can be dressed up or juice.
With note, method of production of PET bottle blowing no stitches, bottle, bao hou uniform can be dressed up fizzy drinks;
Using extrusion blow molding production of PET bottle is suitable for holding fruit juice and mineral water.
Is a research and development, smart, sales, beauty makeup supplies and plastic packing containers of a modern enterprise, focus on the high-end pet plastic bottle production design, excellent products, a small order, welcome to call the advisory.
