PLA Pulp Heat-Resistant Modification
Problem Phenomenon
PLA tableware has insufficient heat resistance, and modification solutions are hard to balance in cost and performance
Cause Analysis
Japan developed pulp-added heat-resistant PLA resin; vinyl copolymer (Biomax Strong) improves toughness; PHA blending improves overall performance; modification generally sacrifices transparency
Solution
①For heat resistance requirements evaluate pulp-modified PLA; ②For toughness requirements select vinyl copolymer modification; ③Transparent parts use modification routes cautiously; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
The common cost of PLA modification is transparency; choose the modification route according to product positioning; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
