VOCÊ SABE COMO SÃO PRODUZIDAS AS PACOTES DE GELO?
Producing a qualified ice pack requires careful design, selection of appropriate materials, strict manufacturing processes, and quality control. The following are typical steps for producing high-quality ice packs: 1. Design phase: -Requirement analysis: Determine the purpose of ice packs (such as medical use, preservação de alimentos, sports injury treatment, etc.), and select appropriate sizes, shapes, and cooling times based on different application scenarios. -Material selection: Choose appropriate materials to meet the functional and safety requirements of the product. The selection of materials will affect the insulation efficiency, durabilidade, and safety of ice packs. 2. Material selection: -Shell material: Durável, impermeável, and food safe materials such as polyethylene, nylon, or PVC are usually chosen. -Filler: select appropriate gel or liquid according to the use requirements of the ice bag. Common gel ingredients include polymers (such as polyacrylamide) and water, and sometimes antifreeze agents such as propylene glycol and preservatives are added. 3. Manufacturing process: -Ice bag shell manufacturing: The shell of an...
