Brief analysis of the factors affecting the quality and price of coffee tins

   Coffee tins occupies an important position in the packaging field, and different quality coffee tins have different prices and different applicable fields. This article introduces you to the factors that affect the price and quality of coffee tins.

       Everyone knows that the prices of coffee tins of different structures and materials are also very different, and the price is closely related to the variety and quality of the raw materials. Making coffee tins is to determine which material is used according to the characteristics of coffee use and transportation conditions. This is a link worthy of attention to maintaining proper packaging and controlling production costs. The raw materials for making coffee tins mainly include: tin-plated iron, galvanized iron, aluminum, etc. The production process of these raw materials and the physical characteristics of the material are different, and the production standards are also different. There are two types of tin-plated iron: frosted iron and silver light iron.

   The quality levels of raw materials for making coffee tins are also divided into three categories: high-quality, first-class and qualified. The test items for coffee tins include: thickness, quantitative, quantitative deviation, banner quantitative difference, tightness, brightness (whiteness), printing surface roughness, smoothness, printing gloss, ink absorption, printing surface strength, water absorption Performance, lateral stiffness and dustiness, etc. The quality of raw materials for coffee tins has a greater impact on printing and strength.

   The author has learned from relevant research institutions that the thickness of coffee tins, the roughness, smoothness and surface strength of the printed surface are more sensitive to the impact of printing quality, and moisture will have a certain impact on the registration of the printing layout. Printing surface roughness, smoothness and surface strength indicators have a greater impact on printing quality, such as whether the printing ink layer can be saturated, and whether the surface can be delamination and blistering after printing. The lateral stiffness of the raw material of the coffee tin can affect the compressive strength of the coffee tin; the tightness of the raw material of the coffee tin is not the higher the better, but the stipulation is not greater than a standard value, such as premium products (quantity ≤ 30 G) not more than 0.88g/cm ³. Because if the tightness of the raw material of the coffee tin is too high, the stamping resistance of the lid will be significantly reduced, and the phenomenon of breakage will easily occur during the stamping process.

    Paper inner trays are mostly used for the inner layer of coffee tins. How the quality of the paper inner support used for the inner layer directly affects the quality of the coffee tin can. The quality standards for the production of inner support are divided into four grades: A, B, C, and D. The quality indicators such as A are the highest. The routine inspection items include thickness, quantitative, tightness, transverse ring pressure index and fracture length, etc., among which the transverse ring Compression index, quantitative and tightness indicators have a greater impact on the edge compression strength of the paper inner support. Among them, the transverse ring compression index, burst resistance index and quantitative impact on the burst resistance, puncture strength and edge compression strength of the paper inner support Obviously, these factors are objective facts proved by the practice of production technology. The prices of coffee tin cans with different quality standards are also different, and high-quality ones are more expensive.

    A coffee tin with an exquisite appearance can always attract people's attention in the first time. In modern society, people pay more and more attention to the appearance of a product. This is because a coffee tin with an exquisite appearance can always attract people in the first time People's eyeballs can better promote coffee sales. A more common form of printing coffee tins, so what factors affect the price of printing coffee tins?

1) The design of printed coffee tins is also a major factor affecting its price. As we all know, the novel design of printed coffee tin can attract consumers' attention and promote product sales. Then the price of a novel design is definitely different from that of an old one. Because the former needs to invite professional designers to design, the price will naturally vary.

2) The different materials for making coffee tins have a great influence on the price of printing. The processes generally used for printing coffee tins are

① In letterpress printing, the graphic part of the printing plate is raised significantly higher than the blank part. The printing principle is similar to that of a seal. Early woodblock printing, movable type printing and later type printing are all letterpress printing.

②Gravure printing, where the graphic part of the printing plate is lower than the blank part, is often used for printing banknotes, stamps and other valuable securities.

③In lithographic printing, the graphic part and the blank part of the printing plate are almost on the same plane, and the printing is carried out using the principle of immiscibility of oil and water.

④ For stencil printing, the graphic part of the printing plate is a hole, and the ink is transferred to the surface of the substrate through the hole. Common stencil printing includes a hollow plate and a silk screen.

   If you want to print coffee tins with better results, you must choose convex printing, so the price difference will naturally be reflected.
