Cigarette BOPP Film Roll Moisture Resistance Film Density 0.91 G/Cm3

BOPP Oriented films can be used as heat-shrinkable films in shrink-wrap applications or can be heat set to provide dimensional stability. Heat sealing is difficult in BOPP films, but can be made easier by either coating the film after processing with a heat-sealable material (such as polyvinylidene chloride) or by coextrusion with one or more copolymers before processing to produce layers of film. Copolymers used in sealing layers must have high gloss and clarity and should have low sealing temperatures to prevent distortion of the oriented polymer during sealing. Random copolymers containing 3–7% ethylene are often used as sealing layers; the lower melting point (<132°C; <270°F) results in a 30% increase in line speeds, and they can be recycled with no significant loss of strength or clarity. Coating or coextrusion increases the barrier properties of BOPP film, decreasing its permeability to gases. Common barrier polymers are ethylene vinyl alcohol, polyvinylidene chloride, and polyamide; five or more layers may be coextruded or laminated, or the barrier polymer can be dispersed in the matrix polymer

Special performance

1) Laminating with other types of substrate material, such as PE, CPP, VMCPP film, for packaging

2) Environmentally friendly: It is environmentally friendly,non-hazardous to health and safe to use as no toxic gases or volatile content is emitted.Safety in laminating process as no solvent based adhesive is used.

3) High function: Compared with other solvent lamination, our film is better in clarity and bonding. Strong ability of absorbing powder, It prevents lamination from being pressed, bubbled and shredded off easily. Matt thermal lamination film is good for spot UV and hot stamping.

4) Adaptable to different kinds of machines: This film is recommended to be used in dry laminator. Small adjustments need to be made to the machine if the film is used in wet laminator.

5) Easy handling:It is easy to operate once the required temperature is met and no special technique required.

6) Efficient and energy-saving: Production cost is reduced substantially as there is no film wastage, mixture of adhesive solvent, and no UV heating lamp is required.

7)laminating with other types of substrate material, such as PE, CPP, VMCPP film, for packaging
