What is the difference between different grams of BOPP thermal synthetic paper?

Different grams of BOPP thermal synthetic paper have significant differences in many aspects, mainly including physical properties, use scenarios, costs and environmental protection. Here's a breakdown of these differences:

First, physical properties

1. Thickness and density

The higher the gram weight of the BOPP thermal synthetic paper, the greater its thickness is usually. For example, 80 grams of BOPP synthetic paper may be significantly larger in thickness than 50 grams of paper. At the same time, due to the different production processes and material formulations, even if the gram weight is the same, different brands of BOPP synthetic paper may have differences in density.

Calendered PP synthetic paper due to the use of calendered process, the product density is high, usually the product density will reach 1.1-1.35, and the bidirectional tensile synthetic paper density is relatively low, the density of BOPP synthetic paper on the market is generally between 0.6-0.8.

2. Strength and toughness

Generally speaking, BOPP thermal synthetic paper with higher gram weight has stronger tensile strength, tear strength and impact strength. This makes them more suitable for use in situations where large forces or wear are required.

Because of its good tension and elongation, the toughness and strength of calendered PP synthetic paper are usually better than that of biaxial tensile synthetic paper.

Second, the use of scenarios

Low weight BOPP thermal synthetic paper: due to its thin thickness and low cost, it is usually used in occasions where printing quality and durability are not required, such as temporary labels, receipts, etc.

High weight BOPP thermal synthetic paper: due to its better physical properties and durability, it is more suitable for long-term storage, withstand harsh environments or high printing quality requirements, such as outdoor billboards, product packaging labels.

Third, cost

Gram weight is one of the important factors affecting the cost of BOPP thermal synthetic paper. Generally speaking, the higher the gram weight, the more materials required, and the corresponding increase in production costs, so the sales price will be higher.

When choosing BOPP thermal synthetic paper, it is necessary to balance the relationship between cost and performance according to actual needs.

Fourth, environmental protection

BOPP thermal synthetic paper, as a substitute for plastic paper, has certain environmental advantages. However, different grams of BOPP thermosensitive synthetic paper may have differences in recycling and degradation performance.

When choosing, you can pay attention to the environmental protection certification and production process of the product and other information to choose more environmentally friendly products.

To sum up, different grams of BOPP thermal synthetic paper have differences in physical properties, use scenarios, costs and environmental protection. In the selection, it is necessary to make comprehensive consideration according to the specific needs and actual conditions.
