What is the production process of a roll of high-quality heat shrinkable film

What is the production process for a roll of high-quality heat shrinkable film? Heat shrinkable film design control includes design input, design output and design review, design verification, design confirmation and design improvement control. Product design control will not only affect the quality of the final product, but also have a considerable impact on the processing technology and cost control of the product. Qualified and reasonable design is the basis for the ultimate efficient production of high-quality products. The control process should include the following factors: design input according to customer, law, and regulatory requirements; design output should be reviewed for compliance with standards, technological advancement, economy, manufacturability, and standardization; design verification control, certification Compliance with design input; design confirmation control, verification record and implementation operation to prove that the heat shrinkable film meets the expected requirements; send to the national authorized inspection agency for review; design changes, whether they are from external or internal changes, should be reviewed And the authorizer approves the change before implementation. Regulatory requirements are an important basis for ensuring safe production, the personal safety of employees, the safety of national property, and the prevention of safety accidents. Environmental protection is also an increasingly stringent requirement in recent years. The development and manufacture of heat-shrinkable film must comply with the provisions of national standards and industry standards, and be inspected by a national authorized inspection agency before being put into mass production and sale. If the product produced by the heat shrinkable film manufacturer does not have a national or industrial standard, the company's product standard should be established. Product standards are the basis for product design, development, production, and acceptance. On the basis of full consideration of customer requirements, regulations and safety standards, product standards should also consider technological advancement, economic rationality and environmental protection. Qualified raw materials and the stability of the supplier's products are the key to ensuring design performance, so it is very important to choose customers with excellent quality assurance capabilities. The following points are worth noting: the selection of the supplier; the evaluation of the supplier’s quality assurance system, supply capacity, complaint handling and service capabilities; the qualified supplier sending samples, a small trial, a small batch trial, and a medium batch trial. Bulk supply; raw materials entering the factory for acceptance; raw material storage; warehouse management.
