PBAT Too Soft, Conveying Difficult
문제 현상
PBAT film has poor rigidity; after blowing, sticking, wrinkling and deviation occur during conveying and bag making, with low bag-making efficiency.
원인 분석
PBAT elongation at break is as high as 750%, too soft; poor film rigidity causes conveying difficulty; improper film roll tension control aggravates deformation; the bag-making machine traction does not match the soft film.
해결 방법
①Blend inorganic fillers such as calcium carbonate and talc to increase rigidity (addition ≤15%); ②Add PLA to increase modulus; ③Optimize the film roll tension control system; ④Adapt bag-making machine parameters to the soft film.
핵심 요약
PBAT's flexibility is a film-forming advantage and a processing disadvantage; filler modification is the main means to increase rigidity; the 15% filler upper limit is the balance point of performance and cost.
