PET polyester material modification of the ten directions
Packaging industry is more and more high to the requirement of plastic packaging materials, for example, in the case of PET polyester film, in order to satisfy the high separation, high brightness, high temperature resistance, hydrolysis resistance, uv resistance, heat sealing, flame retardant, high shrinkage, such as different requirements, the main staff should be PET polyester material modification. ( 1) Using PET + PEN blend or PET/PEN co-extrusion composite to produce high separation, high temperature resistant, anti ultraviolet BOPET film; ( 2) PET/PETG co-extrusion compound is used to produce BOPET film can be heat sealed; ( 3) Use PET + PETG or use PETG and adopt corresponding tension membrane process can produce high shrink film; ( 4) The PET + amorphous polyester or using special additive masterbatch to produce high gloss film; ( 5) Use PET film coated on the surface of high separation resin high separation can be obtained from PET film; ( 6) Use PET film coated on the surface of transparent coating containing uv coated collectors ( Such as epoxy acrylate polymer, polyurethane acrylate and polyester acrylate) , can constitute a polyester film uv protective layer; ( 7) Use PET film coated on the surface of a polymer high surface tension can be obtained from PET film; ( 8) Use PET film coated on the surface of some kind of solution can be made of antistatic PET film; ( 9) Nano-meter composite modified PET can be obtained with high barrier property and thermal stability of PET film; ( 10) Using PET resin containing special functional masterbatch can be obtained with different functions ( Flame retardant, inferior smooth, pearl, antistatic, etc. ) PET film.
How do small and medium-sized enterprises develop product of cosmetics.
1. Don’t make too many products. There are more and more small and medium-sized cosmetic manufacturers. Their products almost cover all kinds of cosmetics. You can see that there are many products, but in fact, they have many disadvantages. The first one is that the sales volume is not necessarily high. The 80/20 law states that 80% of the benefits of any entity come from 20% of the products, that is, 80% of the products can only contribute 20% of the benefits, which is not economic. The second one is that too many product lines are relatively backward in management, and their own strength is insufficient, enterprises can’t grasp the dynamics of consumers' hearts, so there are a lot of products which are not need by consumers. Third, most companies focus on speculation and bargain hunting. Too many product lines limit the development of an enterprise. It is difficult for consumers to form an understanding of the enterprise without a major product. And it is impossible to find the market position without the c
Types and characteristics of cosmetic tube
Tubes are divided into single-layer, double-layer and five-layer tubes, which are different in anti-pressure, anti-penetration and hand feeling. For example, five-layer tube is divided into outer layer, inner layer and two bonding layer, and another barrier layer.
