It's be mainly used for bopp film gelatinizing producing，The tape is mainly used to seal the box, seal the cover and bind the articles, and can also be used as office supplies.
BOPP film data --
Advantages of BOPP film:
BOPP film is a very important flexible packaging material. BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency.
BOPP film has low surface energy and needs corona treatment before coating or printing. After corona treatment, the BOPP film has good printing adaptability, can be printed in color, and has a beautiful appearance effect, and thus is often used as a surface layer material of the composite film.
Insufficient BOPP film:
BOPP films are also insufficient, such as easy accumulation of static electricity, no heat sealability, and the like. In high-speed production lines, BOPP film is prone to static electricity, and an electrostatic remover is required. In order to obtain a heat-sealable BOPP film, a heat-sealable resin glue such as PVDC latex, EVA latex, etc. may be applied after corona treatment on the surface of the BOPP film, or a solvent glue may be applied, or extrusion coating or The co-extruded composite method produces a heat sealable BOPP film. The film is widely used in the packaging of bread, clothes, shoes and socks, as well as the cover of cigarettes and books. The initial tear strength of the BOPP film is improved after stretching, but the secondary tear strength is very low. Therefore, no cuts can be left on both end faces of the BOPP film, otherwise the BOPP film is easily torn during printing and compounding. BOPP can produce sealing tape after coating self-adhesive, which is a market with a large amount of BOPP.
(7) PET shrink film
Polyester heat shrinkable film is a new type of heat shrinkable packaging material. Due to its easy recycling, non-toxicity, odorlessness, good mechanical properties, and especially environmental protection, polyester (PET) has become an ideal substitute for polyvinyl chloride (PVC) heat shrinkable film.
However, the ordinary polyester is a crystalline high polymer, and the ordinary PET film can only obtain a heat shrinkage rate of 30% or less by a special process. To obtain a polyester film with a higher heat shrinkage rate, it must also be modified. That is, in order to prepare a polyester film having a high heat shrinkage ratio, it is necessary to copolymerize a common polyester, that is, polyethylene terephthalate. The copolymerized modified PET film has a maximum heat shrinkage rate of more than 70%.
The characteristics of the heat-shrinkable polyester film: it is stable at normal temperature, shrinks upon heating (above the glass transition temperature), and is more than 70% heat shrinkage in one direction. The advantages of heat shrinkable polyester film packaging are:
1 The body is transparent, reflecting the image of the product.
2 tightly packed with good anti-scattering properties.
3 rain, moisture, mildew.
4 no recovery, there is a certain anti-counterfeiting function. Heat shrinkable polyester film is often used in the convenience food, beverage market, electronic appliances, metal products, especially shrinkage labels are its main application areas. Because with the rapid development of PET beverage bottles, beverage bottles such as cola, sprite, and various juices need PET heat shrinkable film to be used as a heat seal label. They are all polyester-based, environmentally friendly materials, and easy to recycle. use.
In addition to being used as a shrink label, heat-shrinkable polyester film has also been used in outer packaging for daily use products in recent years. Because it can protect the packaged goods from impact, rain, moisture, rust, and the product can win the user with a beautifully printed outer packaging, and it can show the good image of the manufacturer. At present, more and more packaging manufacturers use printed shrink film to replace traditional transparent film. Because the printing shrink film can improve the appearance of the product, which is conducive to the advertising of the product, the trademark brand can make a deep impression on the consumer.
