Many people have given great affirmation after earnestly studying the production technology and development status of pet cosmetic bottles. Nowadays, more and more cosmetics processing factories have abandoned OPP bottles and instead order the praised pet cosmetic bottles. So what are the advantages of pet cosmetic bottles different from OPP bottles? The difference between the two is mainly manifested in the following points
. Different processing yields
The sales volume of pet cosmetic bottles in the market today is higher than that of OPP bottles because the processing yields of these two bottles are different. PET cosmetic bottles can be quickly formed without too high temperature during the injection molding stage of the preform due to their light weight; while the OPP bottle has poor heat absorption and dispersion ability and thicker wall thickness, so it is required during blow molding. Higher temperatures require a lot of time and energy. Therefore, the rejection rate of OPP bottles is much higher than that of pet cosmetic bottles.
.Different rigidity
After comparing pet cosmetic bottles with OPP bottles, many friends will find that the rigidity of OPP bottles is much lower than that of pet bottles. The reason why the OPP bottle is increased in thickness on the bottle wall is to increase its rigidity, thereby increasing its strength and top load. On the contrary, the ordinary thickness of pet cosmetic bottles still meets the rigid requirements of most cosmetics during production and processing. This is one of the reasons why pet cosmetic bottles are eagerly sought after in the market.
. Different permeability
The main component of the material used in the pet cosmetic bottle is polyethylene terephthalate. This material has good abrasion resistance and permeability, so it can effectively prevent carbon dioxide, oxygen and water from entering the bottle. in. The permeability resistance of the OPP bottle is much lower than that of the pet bottle, and it cannot completely prevent gases such as carbon dioxide from entering the bottle, so it cannot be used to store carbonated cosmetics.
The advantages of pet cosmetic bottles different from OPP bottles are very obvious, and many cosmetic processing factories also recognize this difference, so they choose higher quality pet cosmetic bottles for processing and storage. The advantages of this type of pet bottle are mainly manifested in the main aspects such as different processing yields, different rigidities, and different permeability, and there are other more advantageous characteristics in the processing and production process.
