What is the difference in the use of different thicknesses of BOPP synthetic paper?

There are some differences in the use of different thicknesses of BOPP synthetic paper, which is mainly related to its physical characteristics, strength, barrier property and the needs of application scenarios. The following is a specific analysis of the differences in the use of BOPP synthetic paper of different thicknesses:

First, thickness range and classification

The thickness range of BOPP synthetic paper is wide, but the common thickness on the market is mainly concentrated in a certain range. In general, the thickness of BOPP synthetic paper can be adjusted according to specific needs, but the thickest BOPP synthetic paper limit thickness is limited, such as some information pointed out that the market's thickest BOPP synthetic paper is only 0.2mm, while the vast majority of domestic BOPP synthetic paper limit thickness is 0.15mm. In practical applications, different thicknesses of BOPP synthetic paper have different characteristics and uses.

Second, the use of different thicknesses of BOPP synthetic paper is different

1. Thinner thickness (such as less than 0.05mm) :

Use: This thickness of BOPP synthetic paper is usually used for scenes with low strength requirements, such as labels, stickers, packaging linings, etc. Due to its light weight and high transparency, it is suitable as a printing substrate for the production of a variety of exquisite prints.

Characteristics: Thin BOPP synthetic paper has good printing adaptability, transparency and certain water resistance, which can meet the basic packaging and printing needs.

2. Medium thickness (e.g. 0.05mm to 0.15mm) :

Uses: Medium thickness BOPP synthetic paper is widely used in food packaging, medicine packaging, daily necessities packaging and other fields. These packaging needs a certain strength and barrier to protect the product from the external environment.

Characteristics: This kind of BOPP synthetic paper not only has good printing adaptability, but also has a certain tear strength and barrier property, which can meet the packaging needs of moderate strength requirements.

3. Thicker (near or at the limit, such as 0.15mm to 0.2mm) :

Use: Thicker BOPP synthetic paper is usually used for occasions with high strength requirements, such as heavy packaging bags, industrial packaging and so on. In addition, some special purpose BOPP synthetic paper (such as after composite processing) may also meet or exceed this thickness range to meet specific needs.

Features: Thick BOPP synthetic paper has higher tear strength and wear resistance, and can withstand greater external forces and shocks. At the same time, its barrier is also stronger, and can better protect the products in the packaging. However, due to the increased thickness, its transparency and softness may be affected.

Third, summary

Different thicknesses of BOPP synthetic paper have different uses, which mainly depend on their physical properties, strength, barrier properties and the needs of application scenarios. The thinner BOPP synthetic paper is suitable for printing and packaging occasions with low strength requirements; Medium thickness BOPP synthetic paper is widely used in food, medicine and daily necessities packaging fields; The thicker BOPP synthetic paper is used for heavy duty packaging and industrial packaging with higher strength requirements. When choosing BOPP synthetic paper, the appropriate thickness specification should be determined according to the specific needs and use scenarios.
