Multi Co-extrusion Biaxially Oriented Polypropylene BOPP Film for Printing and Lamination

1.INTRODUCTION to BOPP FILM
    Bi-axially Oriented Polypropylene (BOPP) Film is the fine transparent soft plastic packaging material. It belongs to crystalline polymers product, whose crystallinity is increased as a result of the molecular that is bi-axially oriented. Therefor its properties including strength tensile, elastic modulus, impact strength, and elongation at break and folding strength are apparently improved.
    BOPP Film features excellent transparency, high gloss, moisture-proof, light, as well as competitive lower price.
    It also has good clarity, good resistance to UV light, excellent chemical and abrasion resistance, reasonable scuff resistance and a great acid resistance.
    After corona treatment, BOPP Film gets excellent printability and exquisite appearance effect by terms of offset printing. It is usually used as a face-layer product when taking plastic film lamination.
    BOPP Film is widely used to various wrapping,  packaging, printing, lamination and metallization.
    BOPP Film is softer and more flexible than polyester (PET) film.

Use: laminated with paper or PE, for books, wine box and food packaging
Printable: yes
Thickness: 12micron,15micron,18micron, 20micron, 25micron, 27micron, 30micron
Corona Treatment: One or two sides, over 38dynes
for lamination usage, it can be used by the ways of both cold laminating machines and thermal laminating machines.
the suitable adhesion glue are water-based and non-solvent based.
so there are water-based cold lamination film bopp and dry heat thermal lamination fim bopp.

2.FEATURE
- High haze and glossy
- High tensile strength
- Excellent ink and coating adhesion
- Low static surface
- Symmetrical thickness
- Easy to open the bag mouth
- Suitable for all kinds of printing
 

3.CLASSIFICATION

According to application, BOPP Film is classified into:
1.    Plain BOPP Film:
Glossy film, used to printing, lamination (transparent and matte), coating (adhesive tape and PVDC coating base film). This film sees most consumption and capacity among the plastic thin films.
2.    Heat Sealable BOPP Film
Used to normal packaging, such as for cigarette, three-layer heat sealable, five-layer vapor barrier, pearlized and coating.
3.    Label BOPP Film
Used to merchandize labels, advertisement printing, books and magazines, bottle label and overall packaging.
4.    Metallic BOPP Film
Used to vacuum metallization
5.    Capacitor BOPP Film
Used to capacitor and metallic capacitor
 
According to film type, BOPP Film is classified into:
1.    Printing BOPP Film
2.    Lamination BOPP Film
3.    Bag Making BOPP Film
4.    Adhesive Tape BOPP Film
5.    Cigarette BOPP Film
6.    Matte BOPP Film
7.    Heat Sealable BOPP Film
8.    Pearlized BOPP Film
9.    Capacitor BOPP Film
10.  Anti-counterfeiting BOPP Film
11.  Transfer BOPP Film
