We have seen a lot of products in our life, and also know a lot about the various packaging. But do you know what's the material selection in those package?
1. Paper packaging materials
In the entire packaging design and development process, paper packaging materials is a universal packaging material widely used in production, life practice. Paper cost is low, suitable for large quantities of mechanized production, and good formability and folding, suitable for fine printing, and has recyclable, economic and environmental advantages.
l Kraft paper
Kraft paper in strong but pliable texture, inexpensive price, with good folding and water resistance. Often used for making shopping bags, food bag, envelopes, cement bags etc.
l Coated artpaper
Coated paper mainly refined from wood, cotton fiber and other high-grade raw materials and divided into two kinds of: single face coated( C1S paper) and double face coated(C2S paper), Applicable to multi-colors pattern printing, in bright and vivid, rich levels of change. Commonly used in the production of handbags, kinds of gift bag, shopping bag, business cards and books cover, magazines etc, also for color paper box making.
l Grey card
Grey card( technically called CCNB) is a paper in one side white and other side gray, cheaper than coated artpaper, with hard& thick texture, good strength, surface strength, folding resistance and printing adaptability, suitable for low valued color paper packaging box, inserts etc.
l Corrugated paper
Corrugated paper has the advantages of strong strength, high load and pressure resistance, shockproof, moisture-proof and so on. A single corrugated board is generally used as a protective layer for the packing of goods or making light cards and pads to protect the vibration or impact of the goods in the stored transportation process; 3 layers(single wall) or 5 layers(double wall) corrugated board for the sale of goods packaging; 7 layers(triple wall) or 11 layers(quadruple wall) corrugated board are mainly made of mechanical and electrical products, furniture, motorcycles, large appliances, etc.
2. Plastic packaging materials
Plastic has good waterproof, moisture resistance, oil resistance, insulation, and light weight, can be colored, easy production, can shape a variety of shapes and adapt to the printing, its rich raw material sources, low cost, good performance, has become in recent 40 years the world's fastest growing packaging materials, is the modern sales packaging one of the most important thing in packaging materials.
l General plastic
Common packaging General plastic components are polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS).
l Foamed plastic
Also known as porous plastic, has excellent impact resistance and shock resistance, low thermal conductivity, low water absorption, low hygroscopicity, chemical stability and other characteristics, commonly used in product buffer packaging materials.
3. Metal packaging materials
Metal is widely used in industrial product packaging, transport packaging and sales packaging. Excellent mechanical properties, high strength, with excellent protection against the overall performance, with a special metallic luster, easy to print decoration.
l Steel packaging
Compared with other metal packaging materials, steel sources are abundant, energy consumption and cost are low, with good plasticity and ductility.
l Aluminum packaging
Aluminum is light weight, has good ductility and corrosion resistance, is not easy to rust, the brightness is beautiful and durable, easy to print, processing and recycling.Aluminum is mainly used in sales packaging, the most common such as cans.
4. Glass, Ceramic packaging materials
Glass has a high degree of transparency, impermeability and corrosion resistance, non-toxic, odorless, stable chemical performance, production cost low characteristic, can be made into various shapes and colors of transparent and translucent containers.
Ceramic has good chemical stability and thermal stability, ability of various chemical erosion, high temperature resistant, cold and hot will not have an effect on ceramic rapid change, is the ideal food, chemicals, packaging container.
I believe that these packaging materials are no stranger to everyone. But, usually we have not thought of a wide range of goods is what kind of packaging?
Minglai Packaging today's introduction, I believe for everyone to rise a lot of knowledge on it!
