Hvis det laves til PVA-film for at erstatte traditionel plastfilm, kan det bruges i plastposer, f\u00f8devareemballage og andre omr\u00e5der.<\/p>\n<p style=\"font-weight: 400;\">Ren PVA-film har d\u00e5rlig vandbestandighed og er meget begr\u00e6nset i praktiske anvendelser. Derfor skal den i de fleste tilf\u00e6lde modificeres og fremstilles, f.eks. fremstilling af vandopl\u00f8selige filmmaterialer, hvis vigtigste r\u00e5materialer er PVA-harpiks og oxideret stivelse. I de senere \u00e5r er der blevet lanceret vandopl\u00f8selige milj\u00f8beskyttelsesposeprodukter med PVA, glycerol, stivelse osv. som de vigtigste r\u00e5materialer, som hurtigt kan opl\u00f8ses i vand ved 70 \u00b0C, og nedbrydningshastigheden kan n\u00e5 mere end 90% i et komposteringsmilj\u00f8 inden for 180 dage.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter size-full wp-image-1009\" src=\"https:\/\/joyforce-tech.com\/wp-content\/uploads\/2024\/02\/4-14.png\" alt=\"\" width=\"1046\" height=\"696\" srcset=\"https:\/\/joyforce-tech.com\/wp-content\/uploads\/2024\/02\/4-14.png 1046w, https:\/\/joyforce-tech.com\/wp-content\/uploads\/2024\/02\/4-14-300x200.png 300w, https:\/\/joyforce-tech.com\/wp-content\/uploads\/2024\/02\/4-14-1024x681.png 1024w, https:\/\/joyforce-tech.com\/wp-content\/uploads\/2024\/02\/4-14-768x511.png 768w, https:\/\/joyforce-tech.com\/wp-content\/uploads\/2024\/02\/4-14-18x12.png 18w, https:\/\/joyforce-tech.com\/wp-content\/uploads\/2024\/02\/4-14-600x399.png 600w\" sizes=\"(max-width: 1046px) 100vw, 1046px\" \/><\/p>","protected":false},"excerpt":{"rendered":"<p>Biodegradable plastics represented by PLA and PBAT have begun to usher in an outbreak, and PVA has also quietly entered the ranks of alternatives to traditional plastics and developed various applications.
