1、中文 2128 字 Packaging materials Packaging materials change rapidly on the development of science and technology, but also promote the ever-changing shape of the packaging. The development of aluminum cans technology make the birth of pop cans； flexible packaging drinks are favored by the emergence of

2、composite materials. Familiar with the characteristics of various packaging materials, and reasonably and science use in packaging design to design the beautiful and unique structure, is the necessary professional qualities of a packaging design people. The design and use of packaging materials Deve

3、lopment today, the use of the material in packaging is very broad, from natural to artificial packaging material, from a single material to synthetic materials. In the design of the packaging material scientific, economic and applicability are usually the basic principles in the choice of materials.

4、 At present, the most commonly used packaging materials are four categories: papers, plastic, metal and glass. 1. Paper packaging materials Paper packaging materials is one of the most widely used in packaging industry, its machining convenience, cost low and suitable for mass production mechanizati

5、on, and molding and folding is well, material itself is also suitable for fine print. (1) the type of paper packaging Materials of paper packaging materials can basically be divided into paper, cardboard, corrugated three categories. A. The main types of paper Kraft paper bleaching paper cellophane

6、B. The main types of cardboard Manila cardboard White Board yellow cardboard kraft paper composite processing cardboard C. Corrugated board Mainly by the two parallel plane paper as a page of paper, inside and outside, through the middle nip the Corrugated Roller processed into the core wave corruga

7、ted paper. Paper are glued together by the tile adhesive in the besmeared corrugated peak. Corrugated board are mainly used for boxes outside, to do for the protection of the supply chain of goods, but also smaller corrugated can be used as packaging material sales of goods or merchandise cardboard

8、packaging to the liner and a reinforcement of the role and protection of goods . Corrugated board are many types, such as single-sided, double-sided corrugated board and double-layer or multi-storey corrugated board. The corrugated board-type（ GB6544 86） Type High (m m) Number （ a/300m m） A 4.5 5 32

9、 36 C 3.5 4 36 40 B 2.5 3 48 52 E 1.1 2 94 98 (2) the standard of paper and cardboard paper With the development of the paper making technical， related industry standards gradually emerge, the paper in the production, use, processing and other sectors are more standardized and internationalized. (3)

10、 the performance of the paper and cardboard paper To understand the performance of the paper, rational use the different characteristics of the paper, will play a big role in the ultimate visual effects in packaging design. A. The surface of the paper: Such as smooth, hardness, adhesion, out of the

11、powder and so on. B. Physical properties of the paper: Refers to the quantitative, thickness, strength, bending, texture, softness, non-fold degree of the paper. For example, in the design of glass paste, usually the lines should be in a horizontal direction for the printing and pasting, so that bot

12、tle firmly affixed adhesive, or vertical lines are very easily deformed, foaming, loss and impact the beautiful. C. Printing suitable of the paper: The different qualities of printing paper will have an impact, like smooth, absorption of ink, hardness, and so out of the powder. 2. Plastic packaging

13、materials Since the plastic materials advent in the early 20th century, it has gradually developed into the economy, and widely used as a packaging material, the use increased and the applications field continue to expand year by year. Plastic is a synthetic polymer materials, different with natural

14、 fibers of a polymer material, such as paper and cardboard. Polymer plastic polymers in the different ways of polymerization and composition, will form different forms, will also increase because of polymer materials heat or cool the processing environment, conditions and processing methods of the d

15、ifferent crystalline state, and produce different results, so the final formation of a number of materials, performance of different products. In accordance with the form used for packaging, plastic packaging materials can be divided into two major types of plastic film and plastic containers. For i

16、ts high strength, oily water-strong, high barrier of the characteristics, plastic film has developed into an extensive use of the inner packaging materials and the production bags of material. Usually, the country no more than 0.2 mm thick is made as the distinction to distinguish t sheet to film bo

17、undaries. Based on the use of the different needs, the processing methods of films have a lot of molding, but can basically be divided into single-layer materials and composites two categories. Plastic containers are created a rigid packaging containers in the case of using the plastic as substrate,

18、 it can replace the wood, glass, metal, ceramics and other traditional materials in containers. The advantage is low cost, light weight, can be colored, easy production, chemical resistance, easy molding, and the shortcomings are not of high temperatures and poor ventilation. Plastic containers are

19、molded with the following several major ways: First, Extrusion, Second, injection, Blow is the third. 3. Metal packaging materials Metal packaging materials have began to be applied in the early 19th century, initially to meet the needs of preservation of food at the long-term for the military expedition. With the development of industrialization, and the progress of manufacturing technological, metal packaging gradually become like white spoon packaging form by the people. It can be cut off from
