CPP is a polypropylene film produced by a cast extrusion process in the plastics industry. This type of film is different from BOPP film and belongs to non-oriented film. Strictly speaking, CPP films only have a certain orientation in the machine direction, mainly due to the nature of the process. Excellent clarity and finish on the film by rapid cooling on chill rolls.
Advantages of CPP Film
CPP: It has the characteristics of good transparency, high gloss, good stiffness, good moisture resistance, excellent heat resistance, and easy heat sealing.
CPP has excellent heat resistance. Since the softening point of PP is about 140°C, this type of film can be used in hot filling, retort pouches, aseptic packaging and other fields. In addition, it has excellent acid resistance, alkali resistance and grease resistance, making it the first choice material in the fields of bread product packaging or laminate materials. It is safe in contact with food, has excellent demonstration performance, does not affect the flavor of the food inside, and can choose different grades of resin to obtain the required characteristics.
Main features of cpp
- Lower cost and higher output compared to other films such as LLDPE, LDPE, HDPE, PET, etc.
- Higher stiffness than PE film.
- Excellent moisture and odor barrier properties.
-Multifunctional, can be used as composite base film. - Can be metallized.
- Excellent presentation as food and commodity packaging and outer packaging, allowing the product to remain clearly visible under the packaging.
CPP Film Application
- CPP lamination film use for Garment, knitwear and flower packaging bags; documents and photo album films; food packaging.
2.CPP Metallized film for barrier packaging and decoration. After vacuum aluminum plating, it can be combined with BOPP, BOPA and other substrates to be used for high-grade packaging of tea, fried crispy food, biscuits, etc. - CPP Cooking film has excellent heat resistance. Since the softening point of PP is about 140°C, this type of film can be used in hot filling, retort pouches, aseptic packaging and other fields. In addition, it has excellent acid resistance, alkali resistance and grease resistance, making it the preferred material in the fields of bread product packaging or laminate materials. It is safe in contact with food, has excellent demonstration performance, does not affect the flavor of the food inside, and can choose different grades of resin to obtain the required characteristics.
- CPP Functional film, also called special film,potential uses include: food packaging, candy packaging (twisted conjunctival film), medicine packaging (infusion bags), replacing PVC in photo albums, folders and documents, synthetic paper, Sticker tape, business card holder, ring folder and stand-up bag composite.
- The new application market of CPP, such as DVD and audio-video box packaging, bakery and pastry packaging, vegetable and fruit anti-fog film and flower packaging, as well as synthetic paper for labels.
