With the improvement of consumption level, now merchants also pay more and more attention to the outer package of products, pay more attention to safety and environmental protection, design sense. But having seen so many packages, do you know the most commonly used packing materials?
Let's take a look at the packaging materials you don't know
一、Paper packaging materials
In the whole process of packaging design development, paper packaging materials as a general packaging materials, has been widely used in production, life practice. Paper material cost is low, suitable for mass mechanization production, and good molding and folding, suitable for fine printing, and has the advantages of recycling, economic and environmental protection.
1. Kraft paper
It has high tensile strength, tear strength, rupture work and dynamic strength. Tough and cheap, with good folding resistance, water resistance. Most of the web, but also a flat paper. Can be divided into single light, double light, stripe, no lines, etc., the color of white and brown, mainly used for wrapping paper, envelopes, shopping bags, cement bags, also used for food packaging paper.
2, coated paper
Coated paper also known as printing coated paper. It is mainly made of wood, cotton and other advanced raw materials. Surface coating glazing treatment, in order to increase the smoothness and gloss, divided into one side and two sides of the paper surface and two kinds of cloth. The paper has smooth surface, high whiteness, good ink absorption and inking performance, can reflect all the colors in the spectrum and get the best effect, and small scalability.
Not only that, also divided into single copper (one side coated glazing), double copper, matte copper and other types (matt coated paper is dumb paper, more expensive than coated paper). Commonly used grams are 80g, 105g, 115g, 128g, 157g, 180g, 200g, 250g, etc. Suitable for color printing, mainly used for offset printing, gravure fine line printing, such as advanced picture books, calendars, books and periodicals illustrations. After printing the color is bright, the administrative levels change is rich.
3. Whiteboard
Whiteboard is a kind of paper board with white and smooth front and grey back, which is mainly used for single-sided color printing and then made into cartons for packaging.
Hard and thick, with good upright strength, surface strength, folding resistance and printing adaptability, suitable for making packaging boxes, lining board, handmade products, etc.
4, corrugated paper
Corrugated has light and strong, load and pressure resistance, shock, moisture, and other advantages, and low cost. Single-sided corrugated board is generally used as a protective layer for the packaging of goods or to make a light card, pad to protect goods in storage during the transportation of vibration or impact; Three or five layers of corrugated board for the production of goods for sale packaging; Seven or eleven corrugated board for mechanical and electrical products, furniture, motorcycles, large appliances and other production packaging. Corrugated paper can be divided into A pit, B pit, C pit, D pit, E pit, F pit, G pit seven types, A, B, C pit generally used for packaging, D, E pit generally used for small and medium-sized packaging.
5.Gold and silver paper jam
In order to highlight the quality of printing and packaging products, more and more customers choose to print with gold and silver CARDS. According to years of printing experience, some problems that should be paid attention to in the printing of gold and silver CARDS are sorted out as follows:
The gold and silver card is a kind of special paper, unlike ordinary paper, they are divided into two kinds: bright gold card and dumb gold card, bright silver card and dumb silver card. It is on the basis of single copper paper or gray board paper covered with a layer of gold and silver foil desert medium, this material is not easy to absorb ink when printing, so in printing to use a kind of fast dry ink to print.
Two, plastic packaging materials
he packaging materials used in various commodities are usually disposable. When the commodities are circulated from the production unit to the hands of consumers or opened for use, the packaging materials have fulfilled their mission, recycling or disposal as waste materials.
Therefore, for packaging materials, one is to require good performance, to be able to adapt to the needs of protection and publicity of goods; The 2nd it is to ask its cost to want as far as possible low, in current plastics so-called general purpose plastics, be like polyethylene and polypropylene, they have the common characteristic such as performance is good, production capacity is big, price is low, it is the first choice material of plastic packaging material.
Plastic has good water resistance, moisture resistance, oil resistance, insulation, and light weight, can be colored, easy to produce, can shape a variety of shapes and adapt to printing, its raw materials are rich, low cost, good performance, is one of the most important packaging materials in modern sales packaging.
Common packaging plastic components mainly include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET).
Three, metal packaging materials
Metal is widely used in industrial product packaging, transportation packaging and sales packaging. It has excellent mechanical properties and barrier properties, good comprehensive protection properties, beautiful appearance, good processing properties, rich resources and good waste disposal. Beautiful appearance, special metal luster, easy to print decoration. It is widely used in food packaging, pharmaceutical packaging, commodity packaging, instrument packaging, industrial packaging, ammunition packaging and other aspects. The largest number is used in food packaging.
1, steel packaging
Compared with other metal packaging materials, steel has more abundant sources, lower price, lower energy consumption and cost, and good plasticity and ductility. Its amount of metal packaging materials in the first place.
2. Aluminum packaging
Light weight, excellent processing performance, good ductility and corrosion resistance, not easy to rust, bright and durable, easy to print, processing and recycling. Aluminum is mainly used for sales packaging, the most common such as cans. There are mainly pure aluminum plate, alloy aluminum plate, aluminum foil and aluminum plating film. Have better corrosion resistance, some occasions also better than stainless steel, such as aquatic products aluminum packaging will not be due to the decomposition of sulfur compounds in protein and metal sulfide black adverse phenomenon.
Glass, ceramic packaging materials
Glass has a high degree of transparency, impermeability and corrosion resistance, non-toxic tasteless, stable chemical properties, lower production cost characteristics, can be made into a variety of shapes and colors of transparent and translucent containers. Ceramic has a good chemical stability and thermal stability, can withstand the erosion of a variety of chemicals, high temperature resistance, cold and hot rapid change will not affect the ceramic, is an ideal food, chemical packaging container. Glass and ceramics belong to silicate materials, glass and ceramic packaging refers to ordinary or special glass and ceramics made of packaging containers, such as glass bottles, glass cans, ceramic bottles and jars, jars, POTS and other containers.
1. Glass materials
2. Ceramic packaging materials
Packaging materials are ever-changing. Packaging materials change with each passing day with the development of science and technology, and also promote the ever-changing packaging form.
There are many materials, also used in daily life, such as wood, leather, paper, gray board, fiberboard, EVA, bamboo, cloth, honeycomb paper, special paper, composite paper, adhesive, pearl cotton, thermoplastic foam and so on
