A new PVC sheet processing technology boosts production efficiency by 30%.

Recently, a groundbreaking PVC sheet‑processing technique has drawn significant attention within the industry. By optimizing the extrusion process and employing an advanced temperature‑control system to precisely regulate thermal variations during production, this method ensures more uniform molecular alignment in the extruded sheets, substantially reducing the defect rate. Additionally, a newly introduced high‑speed traction unit boosts production speed by 30% while maintaining product quality. This innovative process is expected to lower the cost of PVC sheet manufacturing and drive growth across the related sector.

PET sheets achieve a better balance of transparency and strength.

Through repeated experimentation, researchers have developed an improved formulation for PET sheets. By incorporating a specific proportion of nano‑scale additives into the raw material and employing a unique blending and stirring process, these additives are uniformly dispersed throughout the PET molecular structure. This not only enhances the transparency of the PET sheets, achieving a light transmittance of over 92%—approaching optical‑grade standards—but also boosts their tensile strength, increasing it by 20% compared with conventional PET sheets. This breakthrough offers a new option for high‑end applications such as premium packaging and optical displays, where PET sheet performance requirements are particularly stringent.

Key progress has been made in the self-healing technology of PE protective films.

A research team has successfully developed a self‑healing polyethylene (PE) protective film. When the surface sustains minor damage such as scratches, the film can autonomously reorganize and repair the affected area under specific temperature conditions, thanks to a unique internal chemical molecular mechanism. The researchers incorporated polymers containing dynamic chemical bonds into the film material; upon damage, the broken bonds are re‑formed in response to thermal stimulation, enabling rapid self‑repair. Currently, this technology has completed laboratory validation and is expected to enter industrial production soon, bringing significant benefits to industries—such as electronics and automotive—that require long‑term surface protection.
