What are BOPET and BOPP films?

BOPP films (Biaxially Oriented Polypropylene Films) and BOPET films (Biaxially Oriented polyethylene terephthalate) are the polyester films that are majorly used for packaging, labeling, and lamination. These films are majorly used in electrical and electronics, pharmaceutical and medical and personal care.

What is uniaxial and biaxial orientation?

The isotropic film is brittle, while uniaxial films yield in the machine direction but are brittle in the transverse direction. The biaxially oriented films exhibit ductile yielding in all directions in the plane of the film.

What is cavitated film?

Cavitated BOPP (Biaxially Oriented Polypropylene) is a type of film used in the food industry to manufacture packaging for ice creams, chocolate bars and bottle labels, among other things. The main feature of this film is the microcavitations – tiny cavities – that are created during film manufacture.

What is the meaning of BOPP film?

Biaxially oriented polypropylene
Polypropylene Films Biaxially oriented polypropylene (BOPP) film is film stretched in both machine and transverse directions, producing molecular chain orientation in two directions.

What is biaxial orientation?

Biaxial orientation is a process whereby a plastic film or sheet is stretched in such a way that the polymeric chains are oriented parallel to the plane of the film.

What is the difference between BoPET and Bopp?

BOPET is more stable through printing and laminating processes than BOPP and is often preferred where high-quality graphics are required. It is the surface film of choice for retort pouches because of its dimensional stability through retort sterilization.

What is the definition of biaxial?

Definition of biaxial : having or relating to two axes or optic axes a biaxial crystal.

What is biaxial oriented?

What is the difference between BOPP and OPP?

OPP stands for Oriented Polypropylene, BOPP stands for Biaxially Oriented Polypropylene and PP stands for Polypropylene. All three differ in their style of fabrication. Polypropylene also known as polypropene is a thermoplastic semi-crystalline polymer. It is tough, strong and has high impact resistance.

Can BOPP film be recycled?

Pellet quality: The high quality recycled BOPP pellets can be put back into production lines such as injection or other applications. The same machine can also process PP and PE (HDPE, LDPE, LLDPE) film waste as well as raffia and woven industrial waste.

What is the difference between CPP and BOPP?

CPP is a soft film like polyethylene, whereas BOPP is a bit stiff and crinkly. CPP does not dead-fold well due to its natural living hinge, whereas BOPP has better dead-fold characteristics.

What is meant by orthorhombic?

Definition of orthorhombic : of, relating to, or constituting a system of crystallization characterized by three unequal axes at right angles to each other.
