BOPP refers to Biaxially Oriented Polypropylene, The production of Polypropylene film is to make the melt of high-molecular polypropylene into a sheet or thick film through a long and narrow head, and then in a dedicated stretching machine at a certain temperature and set speed, simultaneously or in steps A film made by stretching in two vertical directions (longitudinal and horizontal) and subject to appropriate cooling or heat treatment or special processing (such as corona, coating, etc.).

BOPP packaging film

BOPP film is a very important flexible packaging material. BOPP packaging films is colorless, odorless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency.

Advantages of BOPP film for packaging

The two surfaces of the flexible packaging BOPP film have asymmetrical designs with different properties, which can well adapt to high and low speed operation:

High modulus, low static, and good folding parts:

High gloss and low haze, make the cigarette pack pattern clear and bright;

It has the vertical and horizontal shrinkage rate required for high-grade hard-box cigarettes, the packaging film is close to the cigarette box, and the cigarette pack pattern is realistically displayed, and the packaging effect is smooth and beautiful;

With post-shrinkage properties, you can obtain satisfactory packaging results even without a cosmetic device

Advantage of DERFLEX flexible packaging BOPP film

1. 100% original PP raw material, to promise the high tensile strength, tearing resistance & scratch resistance.

2. Achieve high folding quality in the packaging molding process, and can achieve good heat-sealing effect in a short pause time.

3. During heat-sealing processing, no toxic body will be produced; it has the right molding ability for various special-shaped products; the heat-sealing film has high transparency and good gloss, which can clearly display the product appearance and increase purchase desire

4. Not easy to embrittle, durable tear resistance, and ensure that the packaged material will not be deformed for a long time.
