Heat-sealed CPP film Process of customized service

1. Demand communication:
The customer provides product information: product type, size, weight, packaging requirements, etc.
Determine the functional requirements of the film: transparency, heat sealing strength, barrier properties, temperature resistance, etc.
Discuss the design plan: printing pattern, text, LOGO, etc.
2. Sample production:
Make samples according to the parameters and design plan provided by the customer.
The customer confirms the sample effect. If there is any adjustment, it will be modified repeatedly until it is satisfied.
3. Mass production:
After the customer confirms the sample, enter the mass production stage.
Strictly produce according to customer requirements to ensure product quality.
4. Delivery acceptance:
After the production is completed, strict quality inspection is carried out.
Deliver the product to the customer and provide relevant test reports.
