How to choose imported paper suitable for your own needs?

There are many aspects to consider when choosing imported paper materials that suit your needs. The following are some suggestions:

Clarify the purpose of use

Printing purposes: if it is used for printing books and magazines, you can choose imported coated paper or offset paper with high smoothness, good whiteness and strong ink absorption, which can present a clear and bright printing effect; For posters and leaflets, imported cardboard with high gram weight and good stiffness can be considered for easy display and preservation.

Packaging purposes: The packaging paper needs to be selected according to the characteristics of the packaged goods. Such as packaging electronic products, you can choose imported special paper with anti-static performance; To package food, you should choose imported wrapping paper that meets food hygiene standards and has good barrier properties, such as coated paper and aluminized paper.

Special purpose: if it is used for painting and calligraphy, you can choose imported art paper, such as cotton pulp paper and watercolor paper, which can provide unique texture and brushwork effect; For office writing, you can choose imported copy paper or notebook paper with good writing performance and high smoothness.

Considering paper performance

Physical properties: including gram weight, thickness, stiffness, strength, etc. Gram weight determines the thickness and weight of paper. Generally, the higher the gram weight, the thicker and heavier the paper and the greater the strength. Paper with good stiffness is not easy to bend and deform, and is suitable for making products that need to keep shape, such as packaging boxes and folders.

Optical properties: Whiteness, glossiness and transparency are important optical properties. Paper with high whiteness can make the printed content clearer and brighter; Gloss is selected according to demand. For example, matt paper is suitable for creating low-key and soft effects, while high-gloss paper can show gorgeous and eye-catching visual effects. Transparency is very important for some special purpose papers, such as tracing paper and translucent paper.

Chemical properties: Mainly consider the pH value and water resistance of paper. Paper with neutral or weakly alkaline pH value is more conducive to long-term storage and less prone to yellowing and brittleness; The paper with good water resistance can be used in outdoor advertising, packaging wet goods and other scenes, and can be realized by adding waterproof agent or adopting special coating.

Understand the paper material

Wood pulp paper: made of wood, it has the advantages of high strength, good flexibility and strong printing adaptability. It is the most common type of paper and is widely used in printing, packaging and other fields. Different wood types and pulping processes will affect the properties of paper, such as high strength of softwood pulp paper and good softness of hardwood pulp paper.

Straw pulp paper: using herbs as raw materials, such as reeds and bamboo. The cost of straw pulp paper is relatively low, but its strength and durability may not be as good as that of wood pulp paper, and it is often used in some cost-sensitive ordinary printed matter and packaging materials.

Cotton pulp paper: With cotton as the main raw material, the fiber is slender and soft, and the paper has high strength, toughness and water absorption, which is suitable for artistic creation, high-grade book printing and other fields that require high paper quality.

Synthetic paper: made of synthetic materials such as plastic resin, it has the characteristics of waterproof, moisture-proof, tear-proof and chemical corrosion resistance, and can be used for outdoor signs, maps, high-grade gift packaging and other special occasions.

Reference brands and suppliers

Well-known brands: There are many well-known paper brands in the world, such as UPM in Finland, Stora Enso in Sweden, etc. These brands usually have a long history and a good reputation, and their products are stable and reliable, and they can provide a variety of specifications and properties of paper materials to choose from.

Supplier reputation: It is very important to choose a supplier with good reputation. We can evaluate the credibility of suppliers by consulting their customer evaluation, industry reputation and business history. High-quality suppliers can not only provide authentic paper materials, but also provide good after-sales service, such as timely supply and professional technical support.

Consider cost and budget.

Paper price: The price of imported paper varies with varieties, specifications, brands and other factors. Generally speaking, the price of high-end specialty paper is higher, while the price of ordinary printing paper and wrapping paper is relatively lower. When choosing, we should balance the performance and price of paper according to our own budget to ensure that the cost is controlled under the premise of meeting the demand.

Transportation cost: transportation cost and transportation time should be considered when importing paper. The cost of different modes of transportation (such as sea transportation and air transportation) is quite different, and the transportation time will also affect the timeliness of supply. If the time requirement is high, you may need to choose air transportation, but the cost will increase accordingly; If time permits, shipping is a more economical choice.

Get a sample test

Apply for samples: Try to apply for paper samples from suppliers before deciding the final choice. Through actual observation and testing samples, we can intuitively understand whether the appearance, texture and performance of the paper meet the requirements.

Test performance: Conduct relevant tests on the samples, such as printability test, strength test, waterproof test, etc., to accurately evaluate the performance of the paper in actual use. If it is used in a specific professional field, you can also refer to industry standards or ask professional institutions to conduct tests.
