Although there are many raw materials for plastic bottles, the effects and characteristics of plastic bottles vary depending on the raw materials, so please try to compare plastic bottles and plastic bottles.
Features: PE is soft and has a waxy texture to the touch. Compared with the same plastic, the quality is relatively light. The PE health care product bottle has a certain degree of transparency, and the flame when incinerated is blue.
Poison: Non-toxic, harmless to human body.
High-density polyethylene (HARE) sold in the market has a density of 0.945 to 0.9 g/cm3 and a melting point of 125 to 137 degrees.
Linear low density PE (LLARE), density 0.925 g/cm3, melting point 120-125 degrees.
High pressure low density PE (HP-L magnetic), density 0.918 g/cm3, melting point 105-115 degrees
Application of polypropylene (PP): tableware, pots, plastic buckets, thermos bottles, woven bags, etc. for microwave ovens.
Features: high chemical stability, good hygienic performance, high heat resistance. The tableware for the electronic microwave oven is made of plastic.
Poison: Non-toxic, harmless to human body.
This polymer can have three three-dimensional structures: isoregular, regular, random polyakrole, the first two crystalline, the latter cannot. The basic structure of commercially available polypropylene products is that the melting point of the PE packaging bottle is 164 to 170 degrees, the density of the crystalline part is 0.935 g/cm3, and the non-clean part is 0.851 g/cm3.
The disadvantage of PP is that it is easy to age. Now, beat with antioxidants and absorbents such as Corydalis.
Polyester (PET) application: plastic bottles, medicine bottles, cosmetic bottles, oil bottles, and various bottle caps and thermal insulation caps.
Features: good transparency, not easy to be damaged, excellent chemical stability, suitable for packaging a variety of liquid or solid drugs. Excellent shielding against UV rays.
Poison: Non-toxic.
PET plastic bottles are the mainstream of beverage packaging. PET plastic bottles occupy a dominant position in the beverage packaging industry in my country. So far, no plastic bottles have been found to be better than PET. The PP bottle is mainly formed by the one-step method and the 2-step method of heating. The PP bottle formed in the molding machine has the advantages of transparency, robustness and heat resistance, and the price is also lower than that of the advanced material. Possibly 100°C. In the material bottle, high-precision PP plastic bottles can be produced by 0.1% - 0.4% Sandy Ekron reduction nucleating agent, spraying, blowing, injection and other methods. PP plastic bottles can withstand temperature, the bottle shape sensitivity is very good, the safety, hygiene and content of the food taste are not well marked, and the price is cheaper than PET, PS, PE and other materials. PP plastic bottles, the application scale in the beverage packaging market is now close to that of PET bottles, and the skills of plastic resins, anti-penetration agents and mechanical equipment are constantly developing. PP containers can replace glass, PET and PVC containers, and there is a broad market prospect.
