Plastic bags store grapes in small packages, usually in ordinary cold storage. The specific method is to first disinfect the grapes, stack the grapes in boxes, seal them with a large plastic cover, fill in 05% of sulfur dioxide, fumigate for 2 hours, and then uncover the accounts and cool them down to 1°C. Then, the grapes were packaged in 0.04 mm thick polyethylene bags, 1 kg per bag, and the bags were immediately closed. Keep the crisp temperature within the box stable at 0~-1°C.
