Plastic containers have a wide range of applications, including food, medicine, agriculture, and beauty. Today, the editor will take you to understand the application and advantages of plastic containers in the beauty industry.
The beauty industry uses a wide variety of plastic container materials for cosmetics and skincare packaging, which have good plasticity. With their superior performance, low cost, and adaptability to environmental protection, they have rapidly developed in competition with other packaging materials such as glass.
Compared to glass products, plastic bottles have lower density, lighter weight, adjustable transparency, and are less prone to breakage; Plastic bottles have good corrosion resistance, acid and alkali resistance, impact resistance, and high mechanical strength. They are easy to shape and have low production losses. Plastic products are easy to color and can be adjusted according to needs, making it easier to meet packaging design requirements.
Reasons for not filling cosmetics:
Considering the thermal expansion and contraction of the material, it is normal to reserve a section of air.
2. Due to the high air pressure inside the bottle caused by different altitudes in different regions, cosmetics may leak out.
3. The bumps during logistics transportation can easily overflow if filled.
4. There are chemical phenols in perfume, which are very volatile, so half of the capacity of perfume is 75~80%;
If filled to the brim, it is easy for the contents to seep out, which can affect the appearance of the product or cause contamination and render it useless. Excessive pressure can cause the bottle to crack during transportation, and if there are special gases present, it can also explode.
This is the characteristic of the production process and raw materials. The product is produced on a standardized assembly line, and the actual weight is the same as the packaging label, not less than one gram.
