Problems solved by technology

Plastic film cannot be degraded, and its waste can cause serious environmental pollution when it is used in large quantities; in addition, after packaging food with plastic film, it is easy to produce harmful gas and odor, which affects the quality of food
Although glutinous rice paper is edible, its strength is poor, and it is easily damaged and dissolved when exposed to water and moisture. It is not suitable for automatic food packaging machinery operation, and it is still difficult to meet the needs of food packaging.

Abstract

The invention provides an edible packaging film for foodstuff and its process for preparing. The components and percentages by weight of this edible packaging film for foodstuff are as below: 20-50% of pullulan; 20-50 % of gelatin; 1-17 % of auxiliary membraneagne; 0.05-2 % of emulsifier; 0-1 % of pigment; and 0.1-10 % of water. The process for preparing the packaging film includes the following steps: preparing the raw materials for intimate mixing materials, then making the obtained materials pass the colloid mill, homogenize and degass, molding by disgorging and strickling through the film forming machine, then drying them to form the film. The edible packaging film provided by this invention has super mechanical property, gas resistivity, scent retention, water resistivity, oil resistivity and tasty retention, is capable of printing and heat-sealing, and is suitable for automatic operation of appliances of packaging film for foodstuff; and the said packaging film is edible and its wastes can be degraded without pollution to the environment. The preparation technology provided by this invention is of simple process and low factory cost, and there is no discharge of harmful substances in the industrial process, so it is of high safety.

Description

technical field [0001] The invention relates to an edible food packaging film and a preparation method thereof. Background technique [0002] There are two main types of traditional food packaging films: one is plastic film, which is used as direct packaging or outer packaging of food; the other is glutinous rice paper made of starch or gel. Plastic film cannot be degraded, and its waste can cause serious environmental pollution when it is used in large quantities; in addition, after packaging food with plastic film, it is easy to produce harmful gas and peculiar smell, which affects the quality of food. Although glutinous rice paper is edible, its strength is poor, and it is easily damaged and dissolved when exposed to water and moisture. It is not suitable for automatic food packaging machinery operation, and it is still difficult to meet the needs of food packaging. Contents of the invention [0003] The purpose of the present invention is to provide an edible food pac...
