BOPP Film Suppliers
Bi-oriented polypropylene film (BOPP) is generally a multilayer co-extruded film, which is made from polypropylene granules that are co-extruded to form a sheet and then stretched in two directions, longitudinally and horizontally.
Due to the orientation of the stretching molecules, this film has good physical stability, mechanical strength, air tightness, high transparency and gloss, toughness and abrasion resistance, and is widely used as a printing film. The main disadvantage of biaxially oriented polypropylene films is their poor heat sealability, so they are generally used as the outer layer of composite films, such as moisture resistance, transparency, strength, stiffness and printability after lamination with polyethylene films, which are ideal for holding dry food.
As the surface of biaxially oriented polypropylene film is non-polar, with high crystallinity and low surface free energy, its printing properties are poor and its adhesion to inks and adhesives is poor, requiring surface treatment before printing and lamination.Wonder Plastic has been in the BOPP film manufacturing sector for almost 10 years and has a wealth of expertise. This has enabled us to concentrate on perfecting all of our BOPP film manufacturing in order to meet your demands. We collaborate with the top designers in the business to ensure that our creations exceed your expectations. These bottles have fantastic features that make them an excellent purchase to consider. They are built to last and provide the finest performance when in use.

Bi-oriented polypropylene film is light, non-toxic, odourless, moisture resistant, high mechanical strength, good dimensional stability, good printing properties and good transparency. It has the advantages of high transparency, good gloss, good barrier properties, high impact strength and low temperature resistance. The disadvantage is that the film is prone to shrinkage when heat-laminated (except for heat-shrinkable cigarette film which takes advantage of its heat shrinkage properties). It has better overall performance than moisture resistant
BOPP film also has excellent printability. Representative physical properties data are: turbidity <1.5%; gloss >85%; tensile strength ( longitudinal/transverse ) >120/200MPa; elongation at break ( longitudinal/transverse ) <180%/65%; modulus of elasticity of 1700-2500Mpa; brittleness temperature of -50°C.
The Disadvantages Of BOPP Film
- Lower elongation than PP
- Poor heat sealing properties
- Not easy to seal when used independently
- Generally laminated with PE and other films with good heat sealing properties when used.
The Advantages Of BOPP Film
- High tensile strength, good barrier properties, high transparency.
- Due to the orientation of molecules, crystallinity is increased, tensile strength, impact strength, rigidity, toughness, moisture resistance, transparency are all improved, the film’s cold resistance is also improved
- Good air and moisture resistance
- High transparency, good gloss, good printability
- Non-toxic, odourless and tasteless, can be used directly in contact with food and pharmaceuticals.
