Skeleton IML

This Skeleton IML sold directly by YZY is specifically suitable for shaped plastic food storage containers and injection-molded containers. The reinforcing ribs and latch positions on the container body edges will not be covered by the label film, solving the industry pain point of traditional full-page IML labels being prone to wrinkling, bulging, and shifting at the edges of the container body.

Manufacturing process

1. Preliminary structural assessment

2. Pre-printing graphic processing

3. Film printing process

4. Skeleton die-cutting and forming

5. Sorting and quality inspection

6. Customer machine injection molding

Application scenario

Food plastic packaging boxes

Home storage containers

Gift plastic boxes

Cosmetics packaging containers

Customized injection molded products

Differential advantages

1. Avoiding position forming defects

Pre-cutting the membrane materials corresponding to the reinforcing ribs and corner snap locks in advance, during injection molding, the plastic directly comes into contact, eliminating common problems such as bubble formation, wrinkling, and arching at the edge corners in full-page IML, significantly improving yield.

2. Material cost optimization

Our Skeleton IML removes a large amount of blank base films, reducing the consumption of membrane materials. Compared with full-page coverage mold-in labels, large-scale orders can compress the label material cost.

3. Retaining the plastic texture of the main body

The non-printing areas directly display the plastic itself, achieving a "local printing + native plastic" mixed appearance, providing higher design freedom.

4. Adapting to complex box structure

Specifically developed for internal reinforcing ribs of square box bands and other difficult molds, without modifying the customer's existing injection molding molds, IML decoration can be implemented.

5. Continuation of IML safety performance

The printed patterns are wrapped in the plastic layer, not prone to friction and detachment. Food-grade material options can meet the compliance requirements for food packaging.

FAQ

Q1: Is it necessary to modify the injection mold for the Skeleton IML?

A: No, the mold does not need to be changed. The labels can be cut with a hollow design to fit the existing mold structure.

Q2: Can the frame labels only have a small pattern on the box body part?

A: Yes, it is supported. Only the LOGO or local patterns can be retained, and the rest of the areas can be completely hollowed out and removed.

Q3: For food preservation boxes, can you provide food contact testing materials?

A: By using food-grade ink film materials, we can provide compliant testing documents in conjunction.

Q4: Can you design the cutting outline of the frame directly based on the box drawing?

A: Provide the mold/product drawings, and we can complete the assessment of the frame die mold scheme.

Q5: Compared to ordinary full-page IML, how much will the yield of the frame IML increase in mass production?

A: The bubble and crease defects at the reinforcement positions and corners have been significantly reduced. The actual yield depends on the injection molding conditions.

Q6: Can we do a sample run to confirm the actual effect of the frame label injection molding first?

A: Sample runs are supported. We can provide sample boxes of the injection molded product to confirm the appearance and molding state.

Q7: What technical endorsements does your company have for frame IML?

A: We have our own laboratory, multiple patents for in-mold labels, and have passed ISO and BRC system certifications.
