There are various materials of plastic bottles, different materials need to be chosen for different purposes, such as PE/PET/PP, etc. The following is a brief introduction to the commonly used raw materials of plastic bottles
1. HDPE material: its surface is matte/frosted, the original color is translucent, if it is made of light-colored bottles, it will be more resistant to friction and not easy to have scratches; but dark-colored scratches are more obvious. It is widely used in shampoo bottles, shower gel bottles, laundry detergent bottles, motor oil bottles, etc.; at the same time, its corrosion resistance is slightly stronger than that of PET, so it is sometimes used for chemical products.
2. PET material: its surface is reflective/bright, the original color is fully transparent, but its surface is easy to scratch/scratch, it can also be made soft touch, but it needs secondary processing, i.e. the bottle is done and then sprayed into frosted. Because it is shiny, smooth and very good-looking, so it is commonly used in personal care packaging, cosmetics packaging. 3.
3. LDPE material: it has a medium glossy surface, the original color is translucent, softer and extruded with elasticity. It is often used to make squeeze bottles, sauce squeeze bottles.
4. PP material: it is more shiny/smooth, the original color is translucent (similar to the color of candles), hard, friction-resistant, not easy to have scratches. More than 90% of the lids, covers, pump heads, nozzles in our lives are made of PP.
5. PETG material: high transparency, extrusion blowing production process, higher cost, suitable for the production of square / square flat / angular bottles, this material produces bottles, the surface is very flat, diamond-shaped. It is also suitable for the bottles of high-grade personal care products. 6.
6. PLA material: polylactic acid, also known as polypropylene cross-ester, is a polyester polymer obtained by polymerization of lactic acid as the main raw material, is a new type of biodegradable material, it uses renewable plant resources (such as corn) proposed by the starch raw materials made. It is a new type of biodegradable material, which is made from renewable plant resources (such as corn). The starch raw material is glycated to get glucose, then fermented by glucose and certain strains of bacteria to make high-purity lactic acid, and then synthesized by chemical synthesis method to synthesize a certain molecular weight of polylactic acid, which has good biodegradability and can be completely degraded by microorganisms in nature after use, and eventually generates carbon monoxide and water, which does not pollute the environment, which is very beneficial to the protection of the environment and is a recognized environmentally friendly material. The treatment method of common plastic is still burning and cremation, which causes a lot of greenhouse gases into the air, while PLA plastic is buried in the soil to degrade, and the carbon dioxide produced directly into the soil organic matter or absorbed by plants, and will not be discharged into the air, which will not cause the greenhouse effect.
7. PCR material: PCR refers to post-consumer plastic, that is, post-consumer plastic, commonly known as “back to the material”, that is, the recycling of used bottles, and then to make new bottles. This material is good for sustainable development. 8.
8. AS material: it has high transparency and is generally used for vacuum bottles.
9. PTFE material: it is called “plastic king”, its high temperature working temperature up to 280 °, in the low temperature also has a medium mechanical toughness, even if the temperature drops to -196 °, there is still the possibility of 5% elongation. At the same time, it is extremely resistant to corrosion, suitable for a variety of corrosive chemical storage.
