Transparency and Gloss:

BOPET lidding film frequently has enhanced transparency and improved surface gloss. Thus, in the packaging field, BOPET lidding film is frequently utilized for the packaging of high-end goods to enhance the visual appeal.

Thermal Stability:

BOPET lidding film has excellent thermal stability and is ideal for high-temperature situations, while PET film is comparatively more delicate and is significantly compromised by high heat.

3. Application Fields of BOPET Lidding Films and Other PET Films:

PET Film:

Because of its comparatively low manufacturing costs, PET film is extensively utilized in the production of ordinary packaging materials, synthetic fibers, labels, and several other goods, ideal for events where the needs for transparency and strength are not very high.

BOPET film:

BOPET film is generally utilized in high-end packaging that needs high strength, enhanced transparency, and thermal stability, defensive films for electronics goods, thin-film solar cells, and optical equipment. As BOPET film has a sturdier compressive barrier and durability, it has unmatched benefits in several high-performance occasions.
