AI Technical Summary
Technical Problem
Existing fruit packaging cushioning materials suffer from environmental pollution, high raw material costs, high production energy consumption, unstable cushioning effect, and difficulty in adapting to automated equipment.
Method used
Using low-grammage paper-based materials, a composite paper blank is formed through precise humidity control and gradient pressing processes. After molding and shaping, it is naturally dried to prepare a paper-based fruit cushioning pad with a concave-convex cushioning structure.
Benefits of technology
It significantly improves the folding strength and cushioning performance of paper-based materials, reduces raw material costs, enhances product stability and automation adaptability, and meets environmental protection requirements.

Abstract
The invention relates to the technical field of fresh food package processing, in particular to a low-gram-weight paper-based fruit cushion material and a preparation method thereof. The preparation method comprises the following steps: coating multiple layers of low-gram-weight paper with a food-grade adhesive, and preliminarily pressing to obtain a composite paper blank; humidifying the paper blank to control the moisture content to be 12-15%; sequentially pressing the humidified raw paper for multiple times, wherein the pressing pressure is in gradient distribution of increasing and then decreasing; the pressed paper blank is placed in a concave-convex mold to be subjected to mold pressing and shaping; and the blank is naturally dried after being slit, so that the water content of a finished product is maintained at 6%-8%. Through the synergistic effect of accurate water content regulation and control and the gradient pressing process, the folding strength of the product is improved by 25%-50% compared with that of raw paper, and the product can be used as an environment-friendly substitute packaging piece of a foamed plastic net cover.
