Cosmetic packaging tube sealing layer commonly used PE

       

Cosmetic packaging tube sealing layer commonly used PE films and CPP films, flexible packaging bags are usually packaged with an automatic packaging machine, which pairs of heat sealing layer of material made by a higher demand. First, the heat sealing layer material must have good heat-sealing adaptive (heat-sealing strength, low-temperature heat-sealing nature of anti-pollution sealing, heat sealing temperature range and thermal adhesion strength, etc.); followed by the re-fit is good; and finally, must have a good go of automatic packaging films, meaning the material of the thermal cover of finish must meet the requirements of automatic packaging machines, with the appropriate friction coefficient (the friction coefficient of the openings from the resin agents, smoothness agents of the type and content of on the choice).

 

     Whether it's history or culture has a long history. From ancient times, cosmetics packaging tube packaging is inseparable from ceramics, glass, clay jar and other containers. They have a small permeability. Good sealing. Corrosion resistance, strong, cosmetic tube packaging allows long-term storage without deterioration, etc., but there are also some difficult to overcome shortcomings. The first is impatience impact, easy to break; followed by inconvenient to carry, mainly large in size and shape, just a few bottles to take a lot of space, which also led to its storage and transportation costs increase; What is a bottle prices higher, used after become a burden. In recent years, also appeared on the market cosmetic tube packaging plastic bottles, which bottles are easy to overcome the fragmentation and capacity to weight ratio small problems, but can not overcome the capacity of the volume ratio of small problems. And it's sealed glass bottles can not be matched. With composite tube cosmetic packaging flexible packaging bags as packaging, under the premise of ensuring the tightness solve the bottle cosmetic tube packaging capacity of the volume ratio of small problems. So, even though bottled cosmetics packaging tube is still on the market mainstream, but with the cosmetic tube cosmetic tube packaging bag packaging and printing has gradually shown its vigorous vitality. Cosmetic tube packaging and printing based on the above-mentioned advantages of bags, flexible packaging bags on the market will gradually promote the development of flexible package printing has broad market prospects

 

    Cosmetic tube packaging and printing bag with the following features.

 

    (1) The barrier is strong, Bao-xiang effect is good. Simply select a suitable substrate, it can be gas-tight, non-breathable, non-penetrating flavor, without thoroughly solvent.

 

    (2) easy to carry, easy to break, and even more resilient than the plastic bottles, in the extrusion, impact, do not break when dropped.

 

    (3) low cost.

 

    (4) cosmetic tube packaging beautiful shape. Easy to use, its shape, size and structural design to diversify. According to people's daily needs, design 12, 22, half a jin and a series of packaging, use more convenient.
