Biaxially oriented polypropylene (BOPP) film is film stretched in both machine and transverse directions, producing molecular chain orientation in two directions. BOPP film is produced by a tubular process, in which a tubular bubble is inflated, or a enter frame process, in which a thick extruded sheet is heated to its softening point (not to the melting point) and is mechanically stretched by 300%–400%. Stretching in the tender frame process is usually in the machine direction and in the transverse direction, although these ratios are fully adjustable. It is a widely used process, more common than the tubular process, and a glossy, transparent film is produced. Biaxially orientation results in increased toughness, increased stiffness, enhanced clarity, improved oil and grease resistance, and enhanced barrier properties to water vapor and oxygen. Impact resistance, low-temperature impact resistance, and flex-crack resistance are substantially modified. BOPP films are used in food packaging and are replacing cellophane in applications such as snack and tobacco packaging due to favorable properties and low cost.

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.

HNB Tobacco 

Heat-not-burn products, also known as heated tobacco products, only heat tobacco.

The heating process generates a flavorful nicotine-containing vapor. And since the tobacco does not burn, the levels of harmful chemicals are significantly reduced compared to cigarette smoke.

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.
