Special sponge for odorless food packaging

Abstract

The invention discloses a special sponge for odorless food packaging. The special sponge comprises a pair of facing layers with the same structure, a pair of perforated plates with the same structureand a filling layer, wherein the pair of perforated plates are mounted between the pair of facing layers. The special sponge has the beneficial effects that the special sponge for packaging is simplein structure and convenient to prepare; due to the fact that the perforated plates of a silver ion sterilization material is added, the air permeability and the water absorption layer are matched through adopting the principle of heterotopic through hole, the drying and aseptic environment in the package is kept, and the special sponge has advantages of low formaldehyde content and low allergens and residual odors; the formula is improved, the residual taste of a raw material is removed through high-temperature heating and drying at 380 DEG C, and high-purity polyether polyol and high-purity tin (T11) are adopted to be subject to full reaction in the production process, so that chemical residues such as formaldehyde are effectively eliminated; and through improving the existing productionformula and the production process, a product has the advantages of low chemical residues, little unpleasant odors and the like compared with the prior art, so that the health of human bodies is effectively protected.

Description

technical field [0001] The invention relates to the technical field of sponges, in particular to a special sponge for clean-taste food packaging. Background technique [0002] The existing sponges mostly use the following ingredients for production, polyether polyol, TDI, methane, H 2 O. Silicone oil (M580), amine (A33) and tin (T9), and ordinary sponges can be obtained by processing the substances on them, but most of the existing sponges have formaldehyde residues, and when they are used as clean food packaging, they are easy to leave odors , allergens and formaldehyde are harmful to people's health. This is because the purity of common polyether polyols and tin (T9) determines the degree of reaction in the reaction process and the degree of volatilization of chemical materials; Or the use of human body needs to reduce the residual value of chemical raw materials. The use of amine, water and silicone oil determines the residual taste or allergens of sponge raw materials. ...

This is because the purity of common polyether polyols and tin (T9) determines the degree of reaction in the reaction process and the degree of volatilization of chemical materials; Or the use of human body needs to reduce the residual value of chemical raw materials. The use of amine, water and silicone oil determines the residual taste or allergens of sponge raw materials. It is necessary to reduce the taste and allergens in food or human use. In view of this, in-depth research on the above problems , so this case arises
