Upgrading Disposable Lunch Box Production Lines — PLA vs. PET Foam: How to Choose?

As global plastic-restriction policies continue to tighten, traditional PS foamed lunch boxes have been banned or restricted in many countries and regions, placing lunch box manufacturers under urgent pressure to upgrade their production lines. Currently, the two main alternative routes are PLA biodegradable foaming and PET foaming, corresponding to the PLA Foam Sheet Extrusion Line and the PET Foam Sheet Extrusion Line…...

Supercritical CO₂ Physical Foaming vs. Conventional Chemical Foaming — Process Differences & Equipment Selection

The foamed materials industry currently relies on two mainstream forming routes: chemical foaming and physical foaming. Chemical foaming generates pores through gas released by decomposing chemical blowing agents. It features low equipment thresholds and low initial capital investment, but finished products suffer blowing-agent residues, uneven cell sizes and insufficient environmental performance. Supercritical CO₂ physical foaming uses carbon dioxide as the blowing medium, leaving no chemical residues and producing fine, uniform cells....

Common Production Problems & Equipment Debugging Tips for EPE Foam

EPE foam, also known as polyethylene foam, boasts outstanding shock absorption, light weight and corrosion resistance. It is widely used for protective packaging of hardware, furniture, electronic products and gifts. Many factories frequently encounter defects such as uneven foam cells, surface blisters, inconsistent hardness and uneven sheet thickness when operating EPE extruders. Most failures stem from improper raw material treatment and mismatched equipment parameters....

Development of Biodegradable Foaming Technology in Packaging Industry

Driven by global plastic restriction policies, regulations on plastic waste control have been rolled out worldwide, fueling booming market demand for biodegradable packaging. PLA foaming machine has gained wide attention from packaging manufacturers. Conventional EPS and EPE foam offer excellent cushioning at low cost, dominating logistics and product protection for decades. However, they take hundreds of years to degrade naturally and trigger severe soil & water pollution if discarded randomly, with high costs for recycling treatment....
