What is the tensile strength of BOPP thermal synthetic paper?

The tensile strength of BOPP thermal synthetic paper is an important physical property index, which reflects the resistance of the material when subjected to tensile force. The tensile strength of BOPP thermal synthetic paper can be analyzed from the following aspects:

First, material characteristics

BOPP (Biaxially stretched polypropylene) films have excellent physical and mechanical properties, including high tensile strength, impact strength, rigidity, toughness and good transparency. These properties make BOPP films widely used in the field of packaging materials, including as a base material for heat-sensitive synthetic paper.

Second, the specific performance of tensile strength

1. Longitudinal (MD) tensile strength:

BOPP films are stretched lengthwise (machine direction), so their longitudinal tensile strength is usually higher. Specific values may vary depending on product specifications, production processes, and other factors, but in general, longitudinal tensile strength can meet the needs of most packaging applications.

Some data show that the longitudinal tensile strength of BOPP films can reach thousands of Newtons per square millimeter (N/mm²), but it is important to note that these data may be for pure BOPP films, rather than specific thermal sensitive synthetic paper products.

2. Transverse (CD) tensile strength:

Transverse (perpendicular to the machine direction) tensile strength is lower than longitudinal, but still has a higher level. The BOPP film has also been stretched laterally to a certain extent to enhance its overall mechanical properties.

The specific value of the transverse tensile strength will also vary from product to product, but in general, it can also meet the needs of packaging applications.

Third, factors affecting tensile strength

1.Production process: Different production processes will affect the tensile strength of BOPP films. For example, the adjustment of process parameters such as tensile ratio and tensile temperature may change the tensile strength of the film.

2.Additives: During the production process, some additives such as plasticizers and antioxidants may be added to improve the performance of the film. The type and dosage of these additives may also have an impact on tensile strength.

3.Post-treatment process: such as coating, composite and other post-treatment processes may also affect the tensile strength of BOPP thermal synthetic paper.

Fourth, conclusion

In summary, BOPP thermal sensitive synthetic paper, as a product based on BOPP film, has a high tensile strength. However, the specific tensile strength value will vary depending on product specifications, production process and other factors. If you need information on the tensile strength of a particular product, it is recommended to consult the technical specifications of the product or contact the manufacturer for accurate data.

It should be noted that because the thermal synthetic paper may contain other layer structures such as thermal coatings in the structure, the existence of these layer structures may have a certain impact on the overall tensile strength. Therefore, when evaluating the tensile strength of BOPP thermal sensitive synthetic paper, it is necessary to consider the overall structure and the properties of each layer of materials.
