IML Printing and Film Solutions: A 2026 Guide for Food Packaging Buyers

In-mold labeling (IML) has become a dominant decoration technology for plastic containers, especially in food and beverage packaging. With the global IML market projected to reach USD 3.14 billion by 2030 (Grand View Research), procurement professionals are seeking reliable suppliers who combine printing precision, material compliance, and scalable capacity. YZY (Zhejiang Zhongyu Technology Co., Ltd.) is a Chinese manufacturer with 16 years of experience, specializing in IML production for food, daily chemical, and industrial applications. This guide explains what IML is, its key parameters, and how to evaluate suppliers for 2026 sourcing.

What Is In-Mold Labeling (IML)?

IML is a process where a pre-printed label is placed inside a mold before plastic resin is injected, forming a permanent bond between label and container. The label becomes part of the product – resistant to peeling, moisture, and scratches. The ZY-IML Series from YZY is an in-mold label classified under Food Grade IML Label, Daily Chemical IML Label, Industrial IML Label, Yogurt Cup IML, and Paint Bucket IML categories. It is manufactured from PP (polypropylene, food-grade virgin resin) or PE, with film thickness ranging from 30 µm to 100 µm (customizable). Printing is done via high-precision rotogravure with up to 8 colors, maximum width of 1200 mm, and print precision of ±0.1 mm.

Industry Context and Market Drivers

Food and beverage applications accounted for over 41.3% of IML revenue in 2023 (Grand View Research), driven by demand for durable, high-quality labels on yogurt cups, ice cream containers, and beverage cups. Asia-Pacific led the market with a 42.8% revenue share in 2025 (Dataintelo), fueled by dairy and paint industry growth in China and India. YZY’s facility in Wenzhou, China covers 20,000 m², employs 250 staff, and has an annual production capacity of 200,000,000 units. The company’s export business accounts for 30% of total sales, with major markets worldwide.

Step-by-Step: How IML Labels Are Produced

1. Film Selection & Slitting: Choose PP/PE film according to container material and process (injection or thermoforming).
2. Rotogravure Printing: Up to 8 colors applied with ±0.1 mm registration accuracy using food-grade inks.
3. Lamination (Optional): Protective topcoat or matte/gloss finish applied.
4. Cutting & Packing: Labels are die-cut to exact shape and stacked for robotic placement.
5. In-Mold Application: Label is placed in the mold cavity; molten plastic bonds to the label during injection.

Use Cases Across Industries

The ZY-IML Series is designed for the food and beverage industry, with typical application scenarios including injection molding. Specific end-uses include:

• Yogurt Cups & Ice Cream Containers: Moisture-resistant labels that stay intact during freezing and thawing.
• Bubble Tea Cups & Beverage Bottles: Scratch-resistant graphics survive condensation and handling.
• Paint Buckets & Lubricant Containers: Chemical-resistant labels that withstand solvent spills and abrasion.
• Cosmetic Containers: High-gloss or holographic finishes for premium appearance.
