Disclosed are a wear-resistant plastic packaging bag and a process for processing same. The packaging bag comprises an inner environmentally-friendly substrate layer (1), a middle interlayer (2) and an outer wear-resistant layer (3), wherein wear-resistant protrusions (4) are further uniformly distributed on a surface of the wear-resistant layer (3), the wear-resistant layer (3) and the wear-resistant protrusions (4) are both made from a special wear-resistant material, and the wear-resistant layer (3) is integrally formed with the wear-resistant protrusions (4). The processing process comprises: a step S1 of preparing the environmentally-friendly substrate layer (1); a step S2 of preparing the wear-resistant layer (3) and the wear-resistant protrusions (4); a step S3 of preparing a plastic film; and a step S4 of cutting, edge heat sealing and processing by stamping to obtain a wear-resistant plastic packaging bag. The environmentally-friendly substrate layer (1) of the plastic packaging bag is made from polylactic acid, and the production process for polylactic acid is pollution-free, moreover, the product is biodegradable, nontoxic to human bodies and environmentally friendly, and food can be stored therein. The outer wear-resistant layer (3) has an excellent wear-resistant effect, can prolong the service life of the plastic packaging bag and has low production costs.
