What factors should be considered when customizing paper cans?

Customization of paper cans requires comprehensive consideration of many factors. The following is an introduction from the dimensions of function, design, and production:
Functional requirements
Product characteristics: The specifications of the paper cans need to be determined according to the shape, size, and weight of the packaged product. For example, for packaging cylindrical tea, the inner diameter and height of the paper can should be able to accommodate the tea cans, and there should be a certain amount of space margin for easy access; for heavier items, the load-bearing capacity of the paper cans should be considered, and the thickness of the paper material should be increased or a reinforced structure should be adopted.
Storage requirements: If the product has high requirements for moisture-proof and waterproof, the paper cans need to be treated with moisture-proof treatment, such as applying moisture-proof coating, lining moisture-proof paper, etc.; if the product is sensitive to light, the paper cans should have light-shielding properties, and paper with light-shielding materials can be added or light-shielding treatment can be selected.
Usage: Consider whether the opening and closing methods of the paper cans are convenient for users. For example, food paper cans may need to be designed with easy-tear openings or flip covers, and cosmetic paper cans may need to be equipped with suitable inner plugs or droppers and other accessories.
Design requirements
Appearance design: The appearance design of the paper cans is carried out according to the brand style and product positioning, including elements such as color, pattern, and text. For example, cosmetic paper cans can adopt a fashionable and exquisite design style, and food paper cans can use bright, attractive colors and vivid patterns.
Structural design: In addition to the common cylindrical paper cans, they can also be designed into special shapes such as square and special shapes according to needs to increase the uniqueness and attractiveness of the product. At the same time, the upper and lower cover structures of the paper cans and whether they need to be layered should be considered.
Material selection
Paper types: Common ones include white cardboard, kraft paper, gray board paper, etc. White cardboard has good stiffness and a smooth surface, which is suitable for printing exquisite patterns; kraft paper has strong toughness and is environmentally friendly, and is often used for products with high environmental protection requirements; gray board paper is relatively cheap and can be used for cost-sensitive products.
Auxiliary materials: If the performance of the paper can needs to be enhanced, some auxiliary materials may be used, such as plastic film for moisture-proofing, fiber materials for increasing strength, etc.
Production process
Winding process: Spiral winding and seamless winding are two common methods. Spiral winding is fast and low-cost, but there may be a certain gap at the interface; seamless winding can provide a smoother surface and better sealing, but the cost is relatively high.
Printing process: Choose the appropriate printing process according to the design requirements, such as offset printing, flexographic printing, gravure printing, etc. Offset printing is suitable for high-precision, multi-color pattern printing; flexographic printing has a low cost and is suitable for printing simple patterns and texts; gravure printing has the characteristics of bright colors and good durability.
Post-processing process: In order to improve the quality and performance of paper cans, some post-processing processes may be required, such as laminating, glazing, hot stamping, embossing, etc. Laminating can increase the wear resistance and waterproofness of paper cans; glazing can make the surface of paper cans brighter; hot stamping and embossing can improve the grade and texture of paper cans.
Cost control
Material cost: Different paper and auxiliary materials have different prices. On the premise of meeting the product function and quality requirements, cost-effective materials should be selected.
Production process cost: Complex production process and post-processing process will increase the cost, which can be reasonably selected according to actual needs. For example, some simple product packaging can reduce unnecessary post-processing processes.
Order quantity: Generally speaking, the larger the order quantity, the lower the unit cost. When customizing paper cans, the order quantity can be reasonably determined based on market demand and budget.
Environmental protection requirements
Environmental protection of materials: Select recyclable and degradable paper and auxiliary materials that meet environmental protection standards.
Environmental protection of the production process: Understand the production process and equipment of the manufacturer to ensure that the discharge of wastewater, waste gas and waste residue is reduced during the production process to avoid pollution to the environment.
