Method for manufacturing attapulgite preservative corrugated cardboard

Abstract

The invention discloses a method for manufacturing an attapulgite preservative corrugated cardboard. The technical scheme adopts the essential that the attapulgite preservative corrugated cardboard ismade of a seven-layer double corrugated cardboard composite material. The method comprises the following steps: bonding an aluminum-plastic composite film on face paper by adopting a hot press method, and sequentially bonding the lower side of the face paper together with corrugated paper A, sandwich paper, corrugated paper B and inner layer paper through a corrugated cardboard machine; and thencoating attapulgite fruit and vegetable preservative paint on the outer surface of the inner layer paper to obtain the attapulgite preservative corrugated cardboard through natural airing. When a fruit and vegetable preservative packing box made of the attapulgite preservative corrugated cardboard is used for storing and transporting fruit and vegetable products, the packing box can restrain and kill various mildews, bacteria and other putrefying bacteria, have the effects of absorbing ethylene gas, preventing temperature in the box from rising and protecting freshness, can effectively reducethe loss of nutritive materials and water of fruits and vegetables and keeping the original taste of the fruit and vegetable products. The attapulgite preservative corrugated cardboard is suitable formanufacturing various fruit and vegetable preservative boxes, preservative refrigeration and transportation boxes as well as fruit and vegetable aerobic preservative transportation boxes.

Description

technical field [0001] The invention relates to cardboard, in particular to a production method of attapulgite fresh-keeping corrugated cardboard. Background technique [0002] A large number of fruits and vegetables have matured and been put on the market one after another, causing slow sales, backlogs, and price reductions in the main fruit and vegetable producing areas to varying degrees. During the circulation process, a considerable part of the fruits and vegetables produced by farmers' hard work become garbage due to rot and deterioration. [0003] Due to the relatively backward manufacturing technology of fresh-keeping packaging boxes, many high-quality fruits and vegetables have suffered heavy losses during storage and transportation. [0004] It is a very important research topic to vigorously develop fresh-keeping technology so that consumers can eat fresh fruits and vegetables just picked all year round and increase the added value of fruits and vegetables.
