The invention discloses a high-strength anti-stretch packaging bag and a preparation method thereof, and relates to the technical field of packaging bags. The first stretch layer, the inner cushion layer, the second stretch-resistant layer and the outer protective layer, the top of the central composite layer is provided with a stretch-resistant layer 1, the top of the stretch-resistant layer 1 is provided with an inner cushion layer, and the The bottom of the central composite layer is provided with a second anti-stretching layer, and the bottom of the second anti-stretching layer is provided with an outer protective layer. The present invention improves the structural strength of the packaging bag, effectively avoids the wear and tear of the packaging bag due to long use time, enables it to be recycled for a long time, and reduces the impact of the packaging bag on internal items caused by the external environment during use. At the same time, the quality of the packaging bag is enhanced, the tensile strength of the packaging bag is improved, the application range of the packaging bag is wider, and the practicability of the packaging bag is further improved. |
