BOPP is the abbreviation of "Biaxially Oriented Polypropylene", BOPP film is biaxially oriented polypropylene film. BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency.
Commonly used BOPP films include: ordinary biaxially oriented polypropylene film, heat-sealed biaxially oriented polypropylene film, cigarette packaging film, biaxially oriented polypropylene pearlescent film, biaxially oriented polypropylene metallized film, matte film, etc.
The production of BOPP film is to first pass the melt of polymer polypropylene into a sheet or thick film through a long and narrow head, and then in a special stretching machine, at a certain temperature and set speed, simultaneously or step by step A film that is stretched in two vertical directions (longitudinal, transverse) and is made by appropriate cooling or heat treatment or special processing (such as corona, coating, etc.).
BOPP film can be produced by tubular film method or flat film method. The properties of BOPP films obtained by different processing methods are also different. Due to the large stretch ratio (up to 8-10) of the BOPP film produced by the flat film method, the strength is higher than that of the tubular film method, and the uniformity of the film thickness is also better.
In order to obtain better comprehensive performance, multi-layer composite method is usually used in the production process. BOPP can be compounded with a variety of different materials to meet specific application needs. For example, BOPP can be compounded with LDPE, CPP, PE, PT, PO, PVA, etc. to obtain high gas barrier, moisture barrier, transparency, high temperature and low temperature resistance, cooking resistance and oil resistance. Packaging of food, dry food, impregnated food, various cooked food, monosodium glutamate, pancake, rice cake, etc.
(Polypropylene film grade -F5606 , is equivalent to SABIC 521P)
BOPP has the characteristics of lightweight,non-toxic,odorless,moisture-proof,high mechanical strength,good dimension stability and printing performance and so on,which was called QUEEN OF PACKAGE and can be widely used in the packaging of cosmetics,toy, craft and agricultural product.Compared with traditional 10-12 microns BOPP film,it is more transparent and friendly to environment ,and cost is less.
BOPP film is also a very important flexible packaging material. BOPP film has low surface energy and needs to be corona treated before gluing or printing. After corona treatment, BOPP film has good printing adaptability, and can be color-printed to obtain exquisite appearance effect, so it is often used as the surface layer material of composite film.
