1. Lightweight packaging materials take the lead.

Lightweight and convenient packaging materials, that is, the amount of packaging should be reduced as far as possible under the condition of meeting the functions of protection, convenience and sales. Nano packaging paper with low gram weight and high strength and ultra-thin plastic packaging materials will become a new favorite in the market.

2. Food grade safety of packaging materials.

In recent years, reports about inferior packaging have emerged one after another, "PVC preservative film carcinogenic storm", "plasticizer", "bisphenol a" and so on have caused harm to human beings in terms of food safety. Poly (ethylene terephthalate) (PET) resin without bisphenol A, food grade degradable polyethylene plastic, edible starch plastic packaging materials, etc. will be cut out in food packaging.

3. Environmental protection of packaging materials.

For traditional plastic packaging materials, non degradable has always been regarded as the great enemy of environmental protection. In recent years, world-famous companies such as Wal Mart, P & G and Dell are abandoning non degradable plastic packaging materials. In the next few years, non degradable plastic packaging materials will be gradually replaced by environmental protection packaging materials.

The biologically reduced plastic packaging material produced by plantic company is 90% corn starch. BASF in Germany launched degradable polyester resin, which can be used in film production. The extrusion foaming PP sheet of Italy A-MUT company is the latest development of foam plastics products.

4. Intelligent packaging materials have become the development potential.

With the advent of the industrial 4.0 era, the R & D and application of intelligent packaging materials will become a new trend in the development of food packaging and have great market potential. It can be predicted that the future intelligent packaging for food will contain more complex, remote readable non visual information. Security tags and radio frequency identification (RFID) tags are the first examples of electronic tags. In addition to product identification information, production date, price, etc., electronic tags can also be used as time temperature, leakage or freshness indicators.

5. The novelty, diversification and multi-function of packaging materials.

With the intensification of market competition, the difference between similar products is gradually decreasing, the homogeneity of commodity use value is gradually increasing, and the dependence of product sales on external packaging display effect is becoming greater and greater.

In the market demand for new packaging materials, it also shows obvious diversity and richness, which is mainly reflected in the types of raw materials, morphological structure, texture and texture and the combination and comparison between them. Some designers also creatively use deformation, hollowing out, combination and other processing techniques to enrich the appearance of materials, endow materials with new images, and emphasize the aesthetic value of material design.
