According to reports, the development of European food paper products has undergone three major stages:
The first stage was before the Second World War. At that time, European food paper packaging production was at a relatively low level. The quality of food paper packaging was poor, the variety was small and the output was low.
The second stage was from the 50s to the 60s. With the technical progress of food packaging materials, the quality of paper materials has been greatly improved, and the progress of packaging machinery, production equipment, and collaborative technologies has promoted the development of the paper packaging food industry. The quality and output of paper packaging have been greatly improved, and the corresponding packaging system standards have also been improved. These breakthroughs in management and technology have enabled the “paper and wood†packaging improvement work to be realized.
The third stage was from the 1960s to the late 1970s. At this time, the quality of paper food packaging materials was further developed. The strength of paper has basically reached the level that can replace tin cans and aluminum cans, which makes paper food packaging. The application scope and adaptability of the material are stronger. The disposable disposable tableware, paper trays, paper cups, etc. that were developed have greatly promoted the market consumption of paper food packaging containers.
At present, one of the development directions of paper food packaging materials in European countries is to develop and produce multi-functional paper products.
1. Moisture-proof The surface of the paper is soaked and sprayed with waterproof material so that the film is attached to one or both sides of the paper, so that the food packaging paper material has moisture-proof properties. This kind of paper has good printing, folding, bonding and other characteristics at the same time. It can be used like ordinary paper.
2. After the pulp has been chemically treated and a resin with a selectivity has been added, the paper produced can have a fresh effect on foods and fruits and vegetables.
3. Sensing temperature In the pulp, rayon can be added to change the color with temperature. According to the change of the color of the wrapping paper, the ambient temperature is indicated, and the food is effectively stored according to the change of the color of the food packaging bag.
4. After the water has undergone special surface treatment, after the surface of the paper is wetted, the paper is changed from opaque to transparent. Consumers can see the food inside the bag without opening, and they can avoid light in the dry state. Effect.
5. Sterilization, anti-corrosion (including anti-oxidation) Inject bactericidal or anti-corrosion materials into the pulp to prevent bacteria from invading and delay food deterioration.
6. Among the types of other multi-functional food packaging papers, there are materials that are resistant to water, oil, acid, and deodorant.
European high-quality, beautifully designed and versatile food sales paper packaging is worthy of our open-minded learning and learning. With the integration of the world economy, the related industries of food packaging and paper materials in China should learn, absorb and digest foreign advanced technology and experience as soon as possible, increase the intensity of technological transformation and product adjustment, and strive to narrow the gap between our country and advanced countries. The paper originated in our country has made greater achievements in the field of food packaging.
European food packaging overview (a)
First, the rapid development of paper food packaging and packaging containers European food paper packaging, generally use paper boxes, paper bags, paper tubes, paper cans and so on. In European restaurants, the paper used for food packaging is one by one. Among various types of paper packaging, paper bags account for the largest proportion. For example, various grain processed products, flour, rice, rice flour, potato flour, and corn flour have paper bag packaging; on-site production of baked goods, fresh food in supermarkets, and fruits Vegetables are also used in paper bags. For foods such as tomatoes and strawberries that are afraid of pressure, they are packed in cartons and then packed in paper bags. The second most important thing in food paper packaging is paper disposable containers such as paper cups and lunch boxes. In any food restaurant, such as McDonald's, pizzerias, and many fast food restaurants selling fried fish and chips on the streets and at the stations, paper cups and cartons are used mainly for packaging and bagging food. The third largest amount of paper packaging is beverage packaging, and various types of fruit juices, vegetable juices, milk, and yoghurt foods are widely used in paper cans. In addition, paper packaging is also used in the packaging and containers of various cooked foods, fast foods, meat products, snacks, and the like. In Hungary and Germany, the use of paper food packaging materials is greater than the use of our country, the use of objects is more extensive. European food, such as grain, cereal products, fruits, vegetables and other goods, the paper packaging capacity is roughly 0.5kg, 1.0kg, 2.0kg, 4.0kg and 10.0kg several types. There are 1 pint, 2 pint, 4 pint and 0.5 lite, 1 lite for the paper packaging capacity of soft drinks, milk and other liquid foods, and various paper packaging can be recycled after use.
