PET plastic bottle appearance is neat, bottle face is very smooth, thread is complete, no damage, and its crystallinity is very good, no good material conditions, also won't have any reel off raw silk from cocoons. The cosmetic tube plastic bottles are not deformation, also there is no oil inside. Bottle forming degree is very good, transparency is very high, also did not appear black spots, scratches, atomization, pale, hardening of the phenomenon, colored bottles should be color is more uniform, no clear off color. The bottom of the bottle is no sag, and also does not have prominent place, at the bottom of the bottle does not appear rupture phenomenon, no delamination phenomenon. Composed of blow molding processing transparent small plastic bottle, now we see more and more on the market. From food packaging to cosmetics packaging and beverage packaging, we have seen more and more transparent plastic bottles on the market. The advantages of small transparent plastic bottle collection the many.

The first is the small transparent plastic bottle production costs low, the price is cheaper from other packaging material container.

Second is transparent plastic bottles texture plastic laminated tube appearance more and more close to the glass bottles, more and more high-grade.

The third is the transparent plastic bottles non-friable, convenient transportation.

So, how to set transparent plastic bottles wholesale price? First of all, small transparent plastic bottle capacity, capacity size will affect the price of small transparent plastic bottle. Secondly, small transparent plastic bottle style, generally small transparent plastic bottle exquisite style is more complex, also often the higher price. Again, the material of transparent plastic bottles, the material such as PP, PET, different material the price will be different.

Compared with other products packaging, cosmetics packaging higher requirements on the resistance and water resistance of oxygen. On the one hand, water cut fat could contain a mould and yeast, will produce the oxidation of fat, fat hydrolysis, oxidation into fatty acids and triglycerides. Therefore, increase the moisture in oil, on the one hand, can cause oil hydrolysis, on the other hand will accelerate oxidation reaction, automatically provides the microbial living environment, reduce some antioxidants such as multivariate amine vigor.
In addition, some flour products to prevent absorb moisture and cause sclerosis of agglomerate, metamorphism and so on, so a lot of cosmetics packaging needed to block the water into the; On the other hand, some of the water product is used to clean the skin, so must be in a certain period of time to make it keep plastic laminted tube certain moisture content, therefore, must prevent moisture to escape again. Oxygen is the main factor of cosmetics rancidity. Most cosmetics contain grease composition. Oil in the unsaturated bond very easy oxidation and cause metamorphism, rancidity. As long as there is a small part of unsaturated fat oxidation, it could cause oil rancidity completely, so that product quality decline. Therefore in the process of the production, storage and use of cosmetics to try our best to avoid the phenomenon of oil rancidity, prevent oxygen to enter.
