What are the properties of BOPP color synthetic paper changed after it is combined with other materials?

After BOPP color synthetic paper is combined with other materials, its performance often changes in many aspects, which are mainly reflected in the following aspects:

First,Changes in physical properties

1.Strength and toughness: The composite BOPP color synthetic paper may have higher tensile strength and tear strength, because some composite materials such as PET, nylon, etc., have higher mechanical strength, and the overall strength can be further enhanced after composite with BOPP.

2.Barrier properties: By combining with other barrier materials (such as PVDC, aluminum foil, etc.), the resistance of BOPP color synthetic paper to oxygen, water and oil may be significantly improved, which is particularly important for packaging applications requiring high barrier properties.

3.Heat resistance: Some composites such as PET have high heat resistance, and after combining with BOPP, the heat resistance temperature range of the overall product can be improved, so that it can maintain stable performance in high temperature environment.

Second, the change of chemical properties

1.Chemical resistance: The composite BOPP color synthetic paper may have increased resistance to chemicals such as acids, bases, and organic solvents, depending on the chemical stability of the selected composite material.

2.Aging resistance: By adding anti-aging agents or combining with other materials with excellent aging resistance, the service life of BOPP color synthetic paper can be extended and the aging degradation caused by light, oxygen and other factors can be reduced.

Third,the change of optical properties

1.Transparency and gloss: The composite BOPP color synthetic paper may maintain or improve its original transparency and gloss, depending on the transparency and surface treatment of the composite material. Some composite materials such as PET film itself has high transparency, and the overall transparency will not be significantly reduced after composite with BOPP.

2.Color and pattern: By combining with other color materials or printing films, rich color and pattern effects can be formed on the surface of BOPP color synthetic paper to meet diverse market needs.

Fourth, the change of processing performance

1.Formability: The composite BOPP color synthetic paper may have better formability and can adapt to more complex packaging structure design.

2.Heat sealing: BOPP film itself has poor heat sealing, but by combining with materials with excellent heat sealing performance (such as LDPE, LLDPE, etc.), it can give the overall product good heat sealing performance, which is easy to package and seal operation.

Fifth,Changes in practical applications

In practical applications, BOPP color synthetic paper and other materials after composite products are widely used in food packaging, pharmaceutical packaging, cosmetic packaging and other fields. The composite treatment not only improves the physical properties and chemical stability of the product, but also enhances its aesthetics and added value, meeting the market demand for high-quality packaging materials.

It should be noted that the specific degree of change in the performance of the composite BOPP color synthetic paper depends on the type of composite material selected, the control of the composite process and the application requirements of the final product. Therefore, in the actual production process, it is necessary to select and adjust according to the specific situation.
