CPP
or cast polypropylene film is a multilayer polypropylene film with
co-polymer and homo-polymer. It is used as a heat seal layer along with
BOPP or polyester film in a laminate for packing of food articles. CPP
films have been known in the packaging field to be the more elegant
brother of polyethylene film, with higher gloss, greater transparency
and better heat resistance.
CPP films have higher gloss and transparency, higher strength, superior
barrier properties and excellent sealing strength. They are available
with a polished or embossed surface, gloss or matte finish, stiff or
flexible, clear or colored, or in a combination thereof. They are
versatile and the most cost effective films.
Film Storage and Handling
Although CPP films are suitable for use within 4 months from the date
of delivery, it is advisable to rotate film stock. It is recommended
that dry conditions at temperatures below 35 degree C are used for
storage of these films, otherwise a reduction in surface treatment level
may be experienced. On account of the elastic memory of thermoplastic
film, a prolonged period of storage may cause problems of profile and
blocking. The film should be kept in its original wrapping until it is
used and should be kept at room temperature 24 hours prior to
processing. Films are very sensitive and any damage or load on the CPP
roll may cause blocking.
Applications: CPP films and packaging
CPP films are used in household paper packing, stationery packaging,
portfolios and food packaging. In stationer industry, they are used for
photo albums and page protectors. They are used as a lamination layer,
both as sealant and as heat resistant layer and in the pressure
sensitive industry for adhesive coating and diaper closures. Also used
as anti-leak layer for diapers, material for automatic packing of
electrical and hardware products and covering films for audio and video
cassettes, CDs and DVD cases. Ideal for textile industry for packaging
of hosiery, socks, shirts; for floral wraps as sleeves and sheets for
cut flowers, pots, dried flowers; food industry for packaging of bread,
vegetables, and candies. Various packaging products made from these
films are
- Packaging rolls
