BOPP film is a very important flexible packaging material with a wide range of applications. BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency. The surface energy of BOPP film is low, and corona treatment is required before gluing or printing. However, after corona treatment, BOPP film has good printing adaptability, and can be printed in color to obtain exquisite appearance effect, so it is often used as the surface layer material of composite film. BOPP film also has shortcomings, such as easy to accumulate static electricity, no heat sealability, etc. On a high-speed production line, BOPP film is prone to static electricity, so a static eliminator needs to be installed. In order to obtain a heat-sealable BOPP film, heat-sealable resin glue, such as PVDC latex, EVA latex, etc., can be coated on the surface of the BOPP film after corona treatment, solvent glue can also be coated, and extrusion coating or coating can also be used. Co-extrusion composite method produces heat-sealable BOPP film. The film is widely used in the packaging of bread, clothes, footwear, etc., as well as the cover packaging of cigarettes and books. The initial tear strength of BOPP film increases after stretching, but the secondary tear strength is very low. Therefore, no cuts should be left on both ends of the BOPP film, otherwise the BOPP film will be easily torn during printing and lamination. After BOPP is coated with self-adhesive, it can be used to produce sealing tape, which is a market with a large amount of BOPP.
BOPP film can be produced by tubular film method or flat film method. The properties of BOPP films obtained by different processing methods are also different. The BOPP film produced by the flat film method has a higher stretch ratio (up to 8-10), so the strength is higher than that of the tubular film method, and the uniformity of the film thickness is also better.
In order to obtain better comprehensive performance, it is usually produced by multi-layer composite method during use. BOPP can be compounded with many different materials to meet special application needs. For example, BOPP can be combined with LDPE (CPP), PE, PT, PO, PVA, etc. to obtain high gas barrier, moisture barrier, transparency, high and low temperature resistance, cooking resistance and oil resistance. Different composite films can be applied to oily food, delicacy Food, dry food, dipped food, all kinds of cooked food, monosodium glutamate, pancakes and other packaging.
BOPP
a. Name: Biaxially oriented polypropylene film.
b. Colorless, high transparency.
c. Because of the two-way stretching in the production process, its tensile strength and impact strength are very good; so this material is the most commonly used printing material in the packaging industry, and because this material has no heat sealing performance (cannot be sealed ), so it cannot be used as a composite heat-sealing material.
d. Excellent cold resistance and heat resistance, suitable temperature: -40~120 degrees Celsius, melting point 165 degrees Celsius.
e. Excellent water vapor barrier performance, but poor oxygen barrier performance.
f. Commonly used thickness: 20um, 30um, 40um.
g. Most product packaging that does not require high barrier properties can choose this material as a printing material.
Most of the surface layer (usually 2~3 layers) of the outer packaging bag of leisure food (snacks) in the supermarket is made of this material, and those beautiful printing patterns are printed on this layer of material……

Widely used in sealing tapes, double-sided tapes, military tapes, fiberglass, reinforced tapes, self-adhesive labels, gold medals, auto parts, air-conditioning parts and electronic components for a variety of paper BOPP, polyester, metal foil and other substrates Aspects of adhesive products.
BOPP sealing tape is made of biaxially oriented polypropylene film (BOPP) and coated with acrylic pressure-sensitive adhesive. Due to its excellent properties such as strong tensile strength, light weight, and low cost, it is widely used in various packaging, bonding, and fixing purposes. Especially in the sealing of cartons, combined with automatic packaging machines, it has become the mainstream of packaging materials. At present, the conventional colors include transparent, beige, milky white and so on. At the same time, we also produce printing tapes and multi-color tapes of various colors, characters and patterns for high-quality packaging according to customer requirements.
There are two purposes for choosing tape:
- The characteristics of the tape: (viscosity, temperature resistance, holding power, whether there is residual glue, material quality, whether there is roll
Edge phenomenon, masking effect, tensile strength, length, stiffness, color, weather resistance, solvent resistance,
Smoothness, dimensional accuracy, tin penetration (generally not), cohesion) - Scope of application: (electronics, decoration, automobiles, industrial packaging, clothing, circuit boards, electrical insulation, general industrial shielding)
Some of the tapes are as follows: (Please enter the website to see the real picture) - กระดาษกาว
