What is  PP film?

Polypropylene film(PP Film) is referred to as PP film in general. PP films with various properties are created using various production techniques and are used in many industries. contain films primarily from the CPP, OPP, BOPP, and MOPP films. All four of the aforementioned materials are made of PP films, which are manufactured utilizing extruding equipment and PP plastic as a raw material.

Why is the Film Stretched?

Stretching the plastic film is done to increase its dimensional stability, mechanical qualities, gloss, transparency, and gas barrier capabilities.

What Kinds of PP Films Are Common?

• Cast polypropylene, often known as CPP film, is a non-stretching, non-directional flat extrusion film.
• Oriented Polypropylene Film (OPP film): This material is uniaxially stretched in the TD direction.
• Biaxially Oriented Polypropylene, or BOPP film, is a type of plastic that can stretch in both the MD and TD directions.
• Mono Axially Oriented Polypropylene (MOPP) film is a type of uniaxially stretched polypropylene.

(MD direction alludes to the machine direction, which is the film’s longitudinal direction. The transverse direction (TD direction) is the transverse direction of the film.

What is CPP Plastic Flim?

CPP plastic film is appropriate for both traditional and non-traditional packaging applications, including laminated stack designs, side welded seal bags, stand-up bags for food and textile packaging, confectionery twist wrap, and document protection.

Low moisture permeability, good heat resistance, organic drug resistance, direct heat sealing, light-specific gravity, etc. are all benefits of CPP film. It can be utilized as a non-toxic, odorless, tasteless, heat-resistant, moisture-proof, and packaging material. The entire line of products complies with independent units’ safety, hygiene, and food safety examinations.

What are the distinctions between PP and CPP films?

An extruder plasticizes and melts the plastic, which is then extruded through a die with a T-shape for shaping, cast as a sheet onto a chilled casting roll for quick cooling, then pulled and trimmed to wind the product for CPP films

CPP films have the following qualities:

• More rigid than PE film.
• Excellent odor and moisture resistance.
• Specialized formulation to create additional membranes with functionality.
• The production procedure is reasonably environmentally friendly because no solvent is utilized.
• The top option for composite materials is due to their lightweight nature, high strength, high toughness, and great impact resistance.

The main distinction between CPP and OPP film is whether or not the film is stretched. OPP is a stretching procedure that improves the film’s qualities. Although the CPP film is not stretched, the formula can be changed based on customer requirements, expanding its scope of use and causing more alterations. Examples include altering the film’s colour, giving it a matte or glossy surface, making it anti-fog, printing, etc. Different formulas can be used to create a variety of functional PP films.

What distinguishes CPP film from OPP, BOPP, and MOPP films?

CPP Film: Casting film that is not stretched, the formula for which can be individually changed to produce a variety of functional PP films, including anti-fog, anti-static, anti-puncture, and fog mask films.

OPP Film: A transversely stretched, BOPP-like PP film used in tapes, labels, packaging, and other items.

Biaxially oriented polypropylene (BOPP) film: is used to package items like food, clothing, cigarettes, and other daily essentials in bags with good gas barrier qualities.

Longitudinal stretch PP film with high unidirectional tensile strength known as MOPP film is utilized in tire linings, strapping tapes, and item labels.
