No Bubble Packing Film For King Size Cigarette BOPP Film 120mm

No Bubble Packing Film For King Size Cigarette BOPP Film 120mm

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.

Stiffness and its application

When the smoke film stiffness is high, the high folding quality can be obtained in the packaging molding process, and can achieve a good heat sealing effect in a very short pause time, is the prerequisite to improve the packaging speed, suitable for automatic variable speed high-speed packaging machine.

The heat sealing conditions of different cigarette packaging machines are often different, and the heat sealing temperatures of the same type of cigarette machines in different environments are also different.

Therefore, a wide range of heat sealing temperature can ensure smooth operation in a variety of cigarette packaging machine, film has a good adaptability.

Heat sealing temperature range narrow smoke film, in the cigarette packaging machine for heat sealing temperature can adjust the window is very narrow, set heat sealing temperature slightly higher hot mouth will wrinkle, and set heat sealing temperature slightly lower will not close, and heat sealing temperature between a roll and another roll is set different, it is difficult to control the heat sealing temperature.

FAQ

Advantages: high tensile strength, good barrier properties and high transparency.

Due to the molecular orientation, the crystallinity is improved, the tensile strength, impact strength, rigidity, toughness, moisture resistance and transparency are all improved, and the cold resistance of the film is also improved.

Good gas barrier and moisture resistance

High transparency, good gloss, good printability

It is non-toxic, odorless and tasteless, and can be directly used in contact with food and medicine.
