YenSheng Machinery

Engineered by Yensheng Machinery for high-barrier aseptic liquid packaging (dairy, juice, plant-based beverages, and liquid foods), this Extrusion Lamination Line features an inline tandem architecture with 3 laminating stations and dual unwinders.

Designed for seamless one-pass continuous production, the system achieves:

Substrate Lamination: High-precision bonding of heavy paperboard and high-barrier aluminum foil.

Dual-Side Sealing & Coating: Precise extrusion coating on both the outer paperboard (waterproofing/protection) and the inner aluminum foil (food-grade PE/PP heat-seal layer).

Combining superior gas/moisture barriers, high peel strength, and advanced automation, this line complies with strict international aseptic packaging standards, delivering an optimal high-capacity, premium-quality solution.

Advanced Inline AC Coating System: Equipped with an inline Anchor Coating (Primer) unit. By applying a specialized primer coating onto substrates like OPP, it creates a robust molecular bridge that significantly enhances bonding strength between the substrate and the LLDPE extrusion layer, achieving exceptional peel strength.
Wide Material Compatibility: Seamlessly processes film-to-film and film-to-foil laminations (BOPP, PET, CPP, LLDPE, and Aluminum Foil) to meet high standards for barrier properties, freshness, and package appearance.
Tailored for Food Packaging: Ideal for manufacturing food bags, high-barrier pouches, retort bags, and automated packaging films, ensuring hygienic, safe, and stable high-speed production.

Integrating water-based coating with two-layer co-extrusion lamination, this unit is engineered for premium In-Mold Labeling (IML) paper production. It achieves complex multi-layer compounding in a single line, delivering superior moisture resistance, scratch durability, and high adhesion to ensure seamless bonding and vivid graphics during in-mold injection, significantly boosting production efficiency.

Advanced 2-Material 3-Layer Co-Extrusion: Features double-resin co-extrusion technology that perfectly encapsulates a high-content recycled core with virgin outer layers, maintaining structural integrity without compromising quality.
Empowering ESG & Sustainability: Maximizes the utilization of PCR/PIR (post-consumer/post-industrial recycled) plastics, reducing reliance on virgin materials and helping businesses achieve critical sustainability goals.
Carbon Footprint & Cost Reduction: Efficiently consumes recycled resin in the middle layer to significantly decrease raw material expenses while lowering carbon emissions throughout the product lifecycle.
Optimized Appearance & Physical Strength: The virgin outer layers completely seal the recycled core, ensuring a clean visual finish, strong heat sealing, and high-performance cushioning protection.
High-Efficiency & Stable Production: Equipped with precision temperature control and advanced co-extrusion dies, delivering stable continuous output with flexible material blending options for eco-friendly mass production.

Advanced Composite Extrusion: Specially engineered for rigid packaging applications, enabling precise processing of high-strength, hollow sheets with enhanced structural integrity.
Superior Impact Resistance & Protection: Hollow structures to deliver outstanding shock absorption and compressive strength, providing maximum protection for heavy or high-value items.
Optimal Strength-to-Weight Ratio: Precise density control drastically reduces overall sheet weight while maintaining high rigidity and dimensional stability, effectively lowering logistics and handling costs.
Durable & Weather-Resistant: Highly resistant to moisture, chemicals, and environmental wear. The durable board design supports multi-trip reusable packaging, aligning with modern sustainability standards.
High-Efficiency & Continuous Output: Features advanced temperature control and stable high-speed extrusion units, guaranteeing consistent line stability, high productivity, and flexible adjustment for custom specifications.

Engineered for premium coffee cups and paper lunch boxes, this high-efficiency double-sided PE coating machine achieves speeds up to 400 m/min, significantly boosting productivity while ensuring superior water and grease resistance.
