Biaxially Oriented Polypropylene BOPP Film Long Cases Clear Film 76mm Inner Dia
 

BOPP thermal laminating film consists of two layers: one layer of BOPP film and one layer of EVA adhesive. The BOPP film forms the hard outer surface of the film and does not melt at laminating temperature, it provides rigidity and protection for your laminated items; The EVA adhesive layer melts at laminating tempeature and bonds the film onto the subject material
under the pressure of the laminating rollers.

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 co-extrusion 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 co-extrusion 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 co-extruded 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.
