BOPP Film For Cigarette Package 350mm Long Cases Cellophane Clear Color

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 tenter 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 tenter frame process is usually 4.5:1 in the machine direction and 8.0:1 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. Biaxial orientation results in increased toughness, increased stiffness, enhanced clarity, improved oil and grease resistance, and enhanced barrier properties to water vapor and oxygen.

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
