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 --
BOPP is an abbreviation for "Biaxially Oriented Polypropylene", which is a biaxially oriented polypropylene film.
The BOPP film is produced by first forming a melt of high molecular polypropylene into a sheet or a thick film through a narrow machine head, and then simultaneously or stepping at a certain temperature and a set speed in a dedicated stretching machine. A film that is stretched in two perpendicular directions (longitudinal, transverse) and subjected to appropriate cooling or heat treatment or special processing (such as corona, coating, etc.).
Commonly used BOPP films include: ordinary biaxially oriented polypropylene film, heat-sealed biaxially oriented polypropylene film, cigarette packaging film, biaxially oriented polypropylene pearl film, biaxially oriented polypropylene metallized film, matte film, and the like.
In order to obtain better comprehensive performance, it is usually produced by a multi-layer composite method in the production process. BOPP can be combined with a variety of different materials to meet specific application needs. For example, BOPP can be combined with LDPE (CPP), PE, PT, PO, PVA, etc. to obtain high gas barrier, moisture resistance, transparency, high temperature, low temperature, retort resistance and oil resistance. Different composite membranes can be applied to oily foods and precious tastes. Food, dry food, impregnated food, various cooked foods, monosodium glutamate, pancakes, rice cakes, etc.
From usage points:
Matting film---BOPP+ matting powder, product packaging for matting effect
Pearlescent film---BOPP+ pearl powder, used for pearlescent effect packaging, also has other materials of pearlescent film.
(2) PET transfer film
The transfer film is also called a heat transfer film. The transfer film is characterized by high tensile strength, good thermal stability, low heat shrinkage, smooth surface and good peelability, and can be used repeatedly. It is mainly used as a vacuum aluminum plating carrier. After the PET film is placed in a vacuum aluminum plating machine, the rubber film is combined with the paper, and then the PET film is peeled off, and the aluminum molecular layer is transferred to the surface of the paperboard by the adhesive action. A so-called aluminized cardboard is formed. The production process of aluminized cardboard is:
PET base film→release layer→color layer→aluminized layer→glue layer→transfer to cardboard.
Vacuum aluminum-plated cardboard is a kind of high-grade novel packaging material developed with metal-gloss cardboard. This kind of aluminum-plated cardboard has bright color, strong metallic feeling, bright and elegant printing, and can replace the large-area bronzing of printed matter, which has played a icing on the cake for the beautification of goods. Because it adopts the vacuum aluminum plating method, the surface of the cardboard is covered with only a thin layer of 0.25um~0.3um thin and bright and bright, only one-fifth of the aluminum foil layer of the aluminum foil, so that it It has a noble and beautiful metallic texture, and has environmentally friendly properties that are degradable and recyclable. It is a green packaging material. Through the formulation and process adjustment, Jiangsu Zhongda was successfully developed in 2005 and put into the market in large quantities, receiving good economic benefits.
