PP Storage Box IML Label Injection Molding

Considering the daily usage characteristics of storage containers, such as exposure to oil stains, water stains, repeated friction, and low-temperature storage, Zhongyu has optimized the base material and ink system of PP Storage Box IML Label Injection Molding to adapt to the injection molding process of thin-walled and large-curvature PP storage containers, solving common problems such as edge raise up, blistering, color fading, and water detachment of ordinary self-adhesive labels.

Custom IML Waterproof In Mold Label for Household Product Specifications

IML Label Injection Molding Production Process

1. Gravure printing on PET/PP film and Lamination

2. Cutting into standard label sheets

3. Automatic robot places labels into injection mold cavity

4. Plastic melt injection, film and plastic melt into one piece

5. Demold finished IML plastic products directly

Advantages compared to ordinary models：

Unlike general IML film materials, this label has been formulated specifically for household PP storage containers. It takes into account the injection molding fluidity, ink adhesion, and bending resistance, enabling the high-definition presentation of patterns, textures, and gradient colors.

Application scenarios

1. Household PP storage organizing boxes

2. Food-grade fresh-keeping storage containers

3. Daily-use storage containers

4. Industrial parts PP storage boxes

5. Children's toy storage boxes

6. Supermarket retail packaging storage

7. Customized injection molding storage containers

Core selling points

1. One-piece molding without back adhesive, completely solving the problems of edge raise up ing and water blistering.

2. Compatible with thin-walled PP injection molding, resistant to stretching and wrinkling, with stable and controllable production yield.

3. Supports high-definition effects such as gradient, pearlescent, and illustrations, enhancing the product's appearance texture.

4. Resistant to water, oil, low temperature, and friction corrosion, with no color fading or damage over a long period of use.

5. The same material source enables one-piece recycling, no need to peel the label, and is environmentally friendly and more convenient.

6. Enhances the structural strength of the box body, saves raw materials, and effectively reduces production costs.

7. Full process of sample making, parameter adjustment, and trial production, suitable for customer injection molding iteration production.

FAQ

Q1: Can the PP Storage Box IML Label Injection Molding be directly applied to the existing PP storage boxes?

A: No, it must be inserted into the mold during the injection molding process. The finished boxes cannot be equipped with additional labels later.

Q2: How to deal with wrinkling of the labels when making thin-walled PP storage boxes through injection molding?

A: We will adjust the film parameters according to the thickness of the box body and match the injection molding process to reduce the defect rate of wrinkles.

Q3: Can complex pattern effects such as pearlescent, gradient, and illustration be achieved?

A: Yes, multiple special textures and color printing effects can be realized.

Q4: Can the product be used as a food-contact storage box for food preservation?

A: Food-contact grade inks and substrates can be selected to meet the requirements of food storage scenarios.

Q5: Can we do a small batch sample testing for the injection molding effect of the new project first?

A: Sample testing is supported. We can cooperate with the customer's injection molding factory to conduct mold verification.

Q6: Can the labels be used universally for different molds of storage boxes?

A: No, the label size and curvature follow the mold. One set of mold corresponds to one set of labels.

Q7: Can your company provide reference suggestions for the IML label injection molding process?

A: Sure. We can provide practical reference on injection molding temperature and mold design, and assist the customer in debugging and production.
