PP Storage Box Injection Molding IML Label

The PP Storage Box Injection Molding IML Label produced by Zhongyu's factory features a complete process that does not require any glue or auxiliary materials. It has no VOC residue and is suitable for high-end daily use and food storage safety and environmental protection production standards.

Solving the problem

Solve the problem of poor adaptability of traditional label storage boxes to cold and hot environments: The temperature difference shrinkage coefficient of ordinary labels does not match the PP substrate. When alternating between refrigerator low temperature and room temperature, the edges are prone to curl and fall off. The IML integrated structure has no layer separation and detachment.

Eliminating safety hazards

The laminated encapsulated ink does not directly contact the outside world， eliminating the risk of ink evaporation and detachment， which contaminates the stored items. It is suitable for family food storage scenarios.

Process

Customized special film materials specifically designed for thin-walled PP injection molding, precisely matching the injection stretch ratio. The high-stretch areas do not turn white or crack, and are suitable for various shaped storage box mold requirements.

Technology

PP Storage Box Injection Molding IML Label adopts a multi-layer composite printing structure, with the graphic and text layers double-encapsulated. It is resistant to hydrolysis, oil stains, acids, and alkalis, and is suitable for complex household usage conditions.

Mold Adaptation Calibration System

For different molds, adapt the process to the vacuum degree and temperature control parameters to solve the problems of film shifting, displacement, and wrinkling during production with different injection equipment.

Strict Quality Control Testing

1. Injection Process Simulation Testing: Replicate the customer's on-site injection temperature, pressure, and vacuum parameters to verify the adaptability of the film in advance and lock in the optimal production parameters.

2. High and Low Temperature Alternating Durability Testing: Test at -20℃ low-temperature refrigeration and constant temperature cycles to verify that the film layer does not delaminate, bubble, or fade.

3. Chemical Resistance Testing: Simulate the contact scenarios of household cleaning agents and oil stains to test the film layer's anti-corrosion and anti-extrusion performance.

4. High Strength and Durability Testing: 100,000 times reciprocating friction test, with the graphics and text intact without any damage, meeting the requirements of long-term high-frequency use.

5. Stretch Deformation Limit Testing: Test the film material's resistance to cracking and whitening in high-stretch areas such as the corners and curved surfaces of the box body.

6. Batch Consistency Sampling: Sample the size, color, and flatness of each batch of PP Storage Box Injection Molding IML Label to prevent batch differences and ensure stable delivery of the bulk goods.

7. Food Safety Compliance Testing: Special testing of food-grade materials for each batch, without harmful exudation, and in line with home food storage safety standards.
