The functions of cosmetics are becoming more and more detailed, and there are more and more cosmetics with comprehensive functions, the differences are very obvious, and the packaging forms are changeable.
In order to better promote their products, various merchants have classified and packaged cosmetics according to their own characteristics.
Cosmetic tubes commonly used in cosmetic packaging are mainly composed of aluminum-plastic composite tubes, pull-plastic composite tubes and plastic co-extrusion tubes, which can meet the various needs of cosmetic packaging such as hygiene and barrier properties.
Aluminum-plastic composite tubes
Aluminum-plastic composite tubes are aluminum foil and plastic film, which are made into plates through pneumatic composite technology, and then processed into tubes packaging containers through special tube machines. Aluminum-plastic composite tubes are used to package cosmetics with high hygiene and barrier properties. The barrier layer is generally aluminum foil, and its barrier property depends on the pinhole degree of the aluminum foil.
Advantage:
- High barrier properties, aluminum foil has barrier properties such as barrier properties, electrical resistance, water resistance, etc., to prevent external substances from invading the interior of cosmetics, prevent cosmetics from oxidative deterioration, and prevent ingredients such as moisture or essence in cosmetics from diffusing to the outside through tubes, thus ensuring cosmetics the quality of.
- Low cost. To accomplish the same plugging function, aluminum-plastic composite tubes offer less material, cost, and economy than all-plastic composite tubes and plastic coextruded tubes.
All plastic composite tubes
Plastic composite tubes are all plastic components, which are divided into all-plastic non-resistance composite tubes and all-plastic resistance composite tubes. All-plastic non-clogging composite tubes are usually used for low-cost fast cosmetic packaging. All-plastic blocking composite tubes have edge seams on the outside of the tube, and are usually used for low-end cosmetic packaging. The blocking layer can be a multi-layer composite material including EVOH, PVDC, oxide-coated PET, etc. The typical structure of plastic barrier composite tubes is PE/PE/EVOH/PE/PE.
Advantage:
- Environmental protection. Compared with aluminum-plastic composite tubes, all-plastic composite tubes use economical and easy-to-recycle all-plastic sheets, which reduces the environmental pollution of packaging waste, and can produce lower cost after reprocessing recycled all-plastic composite tubes product.
- Various colors. According to the characteristics of cosmetics and consumer demand, all-plastic composite tubes are made in various colors such as colorless transparent, colorful transparent, and opaque colors, which can bring strong visual enjoyment to customers. In particular, transparent all-plastic composite tubes can clearly see the color state of the contents, giving people a strong visual impact and greatly promoting customers’ desire to buy.
- Good resilience. Compared with aluminum-plastic composite tubes, all-cow composite tubes have better resilience. After extruding cosmetics, the tubes will quickly return to their original shape and always maintain a beautiful and regular shape. This is very important for cosmetic packaging.
Plastic co-extrusion tubes
Pneumatic technology is used to combine materials with different functions and varieties, and form them at one time. Plastic total extrusion tubes are divided into single-layer extrusion tubes and multi-layer co-extrusion tubes, which are mainly used for packaging fast-consuming cosmetics (such as hand cream tubes) that have high requirements for appearance and low requirements for actual use functions.
Advantage:
- Without luffing, the appearance is better than composite tubes. Required for high-end cosmetic tubes packaging.
- According to the extrusion mold, various shapes of extrusion tubes (such as oval, square, etc.) can be produced to meet the needs of different customers.
