High Folding Quality Cigarette BOPP Film Roll Moisture Resistance Anti-Fog

High Folding Quality Cigarette BOPP Film Roll Moisture Resistance Anti-Fog

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.BOPP film has a good printing adaptability, can be color printing and get a beautiful appearance, so it is often used as composite film surface material

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.

Operation Guidance

1. Adjust roller pressure and temperature according to different types of paper and ink.

2. When using the film for the first time or changing the usual size, a small trial volume before starting massive lamination is proposed.

3. Normal process temperature is 90C-105C (203F - 221F), roller pressure and temperature vary from different types of paper, ink and machines.

4. Make sure the ink is dry before laminating. It will delaminate when the paper contains too much moisture or powder.

5. Make sure to put the material in place with low temperature and dry.

6. The following situation will affect the final quality of the film during lamination.

a. Using metal ink

b. Ink containing too much wax, dried oil, adhesive, silicon additive and so on.

c. Much too thick ink

d. Ink completely not dried yet.

e. Much too humid paper sheet.

f. Too much powder on the surface
