Types and characteristics of plastic hoses commonly used in cosmetic packaging

The functions and effects of cosmetics are becoming more and more refined, and there are more and more cosmetics with comprehensive functions. The differences in levels are very obvious, and the packaging forms are dazzling; at the same time, in order to promote their products, various merchants have made different cosmetics. Classification and packaging suitable for your own characteristics. Plastic hoses commonly used in cosmetic packaging are mainly composed of aluminum-plastic composite hoses, pull-plastic composite hoses and plastic co-extruded hoses, which can meet various needs of cosmetic packaging such as hygiene and barrier properties.

1. Aluminum-plastic composite hose

Aluminum-plastic composite hose is made of aluminum foil and plastic film. It is made into a plate through a pneumatic composite process, and then processed into a tubular packaging container by a special tube machine. The curved structure is PE/PEEAA/AL/PE EAA/PE. Aluminum-plastic composite hoses are mainly used to dry-pack cosmetics with high hygiene and positive barrier properties. The negative barrier layer is usually aluminum foil, and its positive barrier properties depend on the pinhole degree of the dry aluminum foil. With the continuous advancement of technology, the thickness of the aluminum foil shielding layer of aluminum-plastic composite hoses has been reduced from the original 40m to 12m or even 9m, thus greatly saving resources.

Aluminum-plastic composite hose has the following advantages during use:

(1) High barrier properties, aluminum foil has barrier properties, resistance, water resistance and other blocking functions to prevent external substances from intruding into the interior of cosmetics, preventing oxidative degradation of cosmetics, and preventing moisture or

Ingredients such as fragrance are diffused to the outside through the hose, thereby ensuring the quality of cosmetics.

(2) Low cost. In order to accomplish the same plugging function, aluminum-plastic composite hoses provide less material, lower cost, and economy than all-plastic composite hoses and plastic co-extruded hoses.

2. All plastic composite hose

All-vegan composite hoses are made of plastic and are divided into all-vegan non-blocking composite hoses and all-vegan block composite hoses. Vegan non-clogging composite hoses are often used for low-cost and fast cosmetic packaging. Vegan barrier composite hoses have edge seams on the outer tube and are generally used for mid- to low-level cosmetic packaging. The barrier layer can be a multi-layer composite material including EVOH, PVDC, oxide-coated PET, etc. The typical structure of plastic barrier composite hose is PE/PE/EVOH/PE/PE

The advantages of plastic composite hoses include:

(1) Compared with aluminum-plastic composite hoses, vegan composite hoses use economical and easy-to-recycle vegan plates, which reduce environmental pollution from packaging waste. After reprocessing the recycled vegan composite hoses, lower-cost products such as cosmetic hoses can be produced.

(2) Various colors. According to the characteristics and consumer demand of cosmetics, all-plastic composite hoses are made in a variety of colors such as colorless and transparent, colorful and transparent, and opaque, which can bring strong visual enjoyment to consumers. In particular, the transparent all-plastic composite hose can clearly see the color state of the contents, giving people a strong visual impact and arousing customers' desire to buy.

(3) Good resilience: Compared with aluminum-plastic composite hoses, all-cow composite hoses have good resilience. After extruding cosmetics, the hose quickly returns to its original shape and always maintains a beautiful and regular shape. This is very important for cosmetic packaging. Plastic co-extruded hose Plastic co-extruded hose uses pneumatic technology. Xu Lu combines different functions and types of materials to form them in one go. Plastic extrusion hoses are divided into single-layer extrusion hoses and multi-layer co-extrusion hoses. They are mainly used for packaging fast-consuming cosmetics (such as hand cream, etc.) that have high requirements on appearance but low actual performance requirements.

The main advantages of plastic co-extruded hose include:

(1) There is no amplitude change and the appearance is better than that of composite hoses. Required for cosmetic tube packaging.

(2) According to the extrusion mold, extruded hoses of various shapes (such as oval, square, etc.) can be produced to meet the needs of different customers for cosmetic hoses.
