Tape packaging materials, Types and Features Overview
Tape packaging materials, Types and Features Overview
Packaging material refers to packaging containers and packaging, shipping, packaging and decoration, packaging, printing, packaging and general auxiliary materials used in the manufacture of packaging related materials. Packaging materials generally include primary packaging materials and auxiliary packaging materials commonly used paper, metal, wood, plastics, textiles, ceramics, glass, grass, bamboo, rattan, wicker, etc., especially the most complex plastic and metal materials.
Packaging materials plays an important role in the whole packaging industry, packaging technology is an important foundation for the development, improve the quality of packaging and reduce packaging costs. Therefore, understanding performance, application and development trend of packaging materials for the rational use of packaging materials, expand the sources of packaging materials, the introduction of new packaging materials and processing technology to create new packaging containers and packaging techniques, improve packaging technology and law They have important and far-reaching significance.
First, the performance of packaging materials
From the functional point of view of modern packaging, packaging materials should have the following several aspects of performance:
(A) protection performance
Packaging material should have a certain mechanical strength, changes in temperature, can be moisture-proof, waterproof, anti-corrosion, anti-UV penetration, heat, cold, light, oil, etc., but itself should be no odor, non-toxic, odorless, can protect the contents good material quality.
(B) operational performance
Packaging material should have a certain rigidity, heat resistance and anti-static properties, there is a certain smoothness and plasticity, weldability, easy to open, easy processing, easy to fill, easy switching, suitable for automatic packaging machine operation, high production efficiency .
(C) the added value of performance
Packing increases the added value of goods, good packaging commodity value and use value greatly. Especially as sales of packaging materials, requiring transparency, surface gloss, so beautiful shape and color, resulting in display effect, in order to increase the value of goods and consumers' desire to buy.
(Iv) facilitate the use of performance
No matter what kind of material packaged goods, the basic requirement is easy to open and extract the contents to facilitate re-closing, opening performance, easy to break and damage.
(V) reduce the cost of performance
Packaging behind both increased costs and achieving the desired effects, it is not desirable. When what packaging materials and methods of practical application options, in addition to considering the several requirements, it must also consider the cost saving packaging materials and packaging machinery and equipment costs, labor costs, etc., to use the most suitable materials, to take the most reasonable packaging method to obtain the best results.
(Vi) the nature of the goods Adaptability
Packaging, must adapt with the nature of the goods. Such as silk piece goods, some to meet directly with customers in the store, while others are made into clothes or finishing processing plant, the packaging should be different, the former should be made more sophisticated, in order to highlight the characteristics of quality silk, which requires flat cargo does not wrinkle, easy unsealed to facilitate processing factory. Another example is a polyurethane foam-pad technology, is a relatively new scientific and technological achievements, with which you can increase the worth of goods, commodity security protection, but need to use this package individually molded, high cost, and time-consuming, it is currently only used for packaging rare and precious crafts sculptures antique porcelain, and general crafts such as wood carvings, ornaments, etc. are polyethylene and plastic bubble film packaging is sufficient.
Second, the main characteristics and application of packaging materials
(A) Paper and paperboard
Paper and cardboard are the backbone of traditional packaging materials, consumption, wide range of applications, its output value accounted for about 45% of the package's total. Paper and paperboard has the following characteristics:
1. It has suitable strength, impact resistance and abrasion resistance.
2. Good sealing, easy to do clean.
3. Has excellent moldability and folding, ease of using a variety of processing methods, should be mechanized, automated packaging production.
4. It has the best printability, ease of introduction and landscaping products.
5. Lower prices, and light weight, can reduce packaging costs and transportation costs 6. Easy to handle after use, recyclable reuse and recycling, will not pollute the environment and conserve resources.
Paper and cardboard are also some fatal weaknesses, such as the difficulty sealing fastness decline and airtight, moisture resistance, transparency and poor damp, making them subject to certain restrictions on packaging applications.
Paper and cardboard containers are mainly large cardboard boxes, cartons, paper bucket, paper bags, paper, cans, cups, trays, etc., it is widely used in transport packaging good sales package. In the paper packaging container up to an amount of corrugated boxes, accounting for more than 50% of its share. In transport packaging, corrugated boxes are replacing the traditional wooden box, widely used in packaging daily necessities, household appliances, clothing and footwear, fruits and vegetables. Currently, corrugated boxes are being standardized to the specifications, functional specialization, reduce weight, increase strength and other direction. In addition to corrugated boxes, other paper packaging containers used for sales packaging, such as for food, medicine, clothing, toys and other daily necessities packaging. Windowed carton can be made, shake-lid, drawer, fit sets, etc., the surface to be decorated, with good exhibition results. Zhitong durable, it can be dressed granular, massive, powdery goods. A wide variety of paper bags widely used. Cups, trays, paper cans are disposable food packaging, since the inexpensive, lightweight, convenience, health, and is widely used. Usually dressed cold cups for small containers. Frozen food packaging trays, both frozen and can be heated in a microwave oven baking. Paper cans made of high-density cardboard, there is a cylindrical, conical, general coating to prevent leakage, for containing beverages, currently consisting of pure paper cans is paper, plastic, aluminum foil composite cans replaced. Pulp molded pulp packaging is directly through the molding dies, drying and made of cushioning material, such as molded plate of eggs for egg packaging, can greatly reduce transport breakage rate.
