Multilayer Films for Food Packaging for Sale - Factory Direct from China, Affordable Prices

1. What Are Multilayer Films for Food Packaging?

Multilayer films for food packaging are advanced polymer-based materials composed of two or more distinct layers, each engineered to fulfill specific functional requirements. Unlike single-layer films, multilayer structures combine diverse polymer resins—such as polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polyamide (PA), and ethylene vinyl alcohol (EVOH)—to achieve a synergistic balance of mechanical strength, barrier properties, heat resistance, sealability, and aesthetic appeal.

• Structure and Composition

• Outer Layers: Often built from high-strength or printable resins (e.g., PET or oriented polypropylene, OPP) that resist abrasion, protect against UV radiation, and provide a high-quality printable surface for graphics and branding.

• Barrier Layers: Typically made from EVOH or metallized films that block oxygen, moisture, aromas, and light, thereby preserving food freshness and extending shelf life.

• Tie Layers: Special adhesive polymers that bond dissimilar resins together, ensuring structural integrity and preventing delamination.

• Sealant Layers: Usually low-density polyethylene (LDPE) or ionomer resins, which offer excellent heat-sealing properties, reliable seal strength, and easy peelability when needed.

• Manufacturing Processes

• Co-Extrusion: Multiple polymer melts are simultaneously extruded through a single die, creating a unified film with layered architecture. Zhucheng Huasu Packing Co., Ltd. employs state-of-the-art five-layer and seven-layer co-extrusion cast film lines, enabling precise thickness control (from 15 μm to 200 μm) and uniform layer distribution.

• Lamination (Dry/Adhesive): Printed or plain films are bonded using solventless or solvent-based adhesives on high-speed dry-lamination machines. Our facility in Weifang employs a six-color plastic printing press and multiple dry lamination lines to produce visually striking and functionally robust packaging solutions.

• Printing & Converting: After film production and lamination, advanced six-color gravure and flexo printing provide sharp graphics. Subsequent slitting, bag-making, and thermal sealing lines transform films into stand-up pouches, vacuum bags, and barrier liners.

• Key Functionalities

• High Barrier Performance: By incorporating EVOH and/or metallized layers, multilayer films achieve oxygen transmission rates (OTR) below 1 cm³/(m²·24 h·0.1 MPa) and water vapor transmission rates (WVTR) under 0.1 g/(m²·24 h), essential for products like cured meats, cheeses, and ready-to-eat meals.

• Mechanical Strength & Puncture Resistance: Polyamide layers impart toughness, ensuring films withstand harsh handling, vacuum packing, and extended storage without tearing or pinholing.

• Thermoformability / Deep Drawability: Specially formulated resins enable deep-draw and thermoforming processes, producing trays and blister packs that maintain shape integrity even under high-temperature sterilization cycles.

2. Product Advantages of Our Multilayer Films

At Zhucheng Huasu Packing Co., Ltd., we leverage over 30 years of polymer extrusion expertise, cutting-edge equipment imported from the United States, and rigorous quality management to deliver multilayer films that outpace international benchmarks.

1. Superior Barrier Protection
   Our five- and seven-layer films integrate EVOH barrier layers (up to 8% by weight), achieving OTR values below 0.5 cm³/(m²·24 h) and WVTR below 0.05 g/(m²·24 h). This level of protection minimizes oxidative rancidity in high-fat products and prevents moisture loss in baked goods.

2. High-Temperature Sterilization Capability
   The high-temperature deep-draw bottom film is engineered to endure retort sterilization at 121 °C for up to 60 minutes without seal failure. This makes our films ideal for retort pouches, ready meals, and long-term storage of cooked meats.

3. Deep-Draw & Thermoforming Excellence
   With precise control of melt strength and molecular orientation, deep-draw films from Zhucheng Huasu consistently form trays with draw ratios up to 3.5× without thinning or tunnel defects, ensuring product consistency and reducing scrap rates.

4. Outstanding Vacuum Retention & Puncture Resistance
   Our multilayer vacuum bags combine PA/PE/PA/PE structures to deliver tensile strength up to 30 MPa and puncture resistance above 25 N. These films maintain vacuum integrity for over six months at refrigerated conditions.

5. Customizable & Cost-Effective
   Through modular layer designs, clients can select barrier level, stiffness, and sealing temperature profiles to optimize cost versus performance. Lower-barrier three-layer films and premium nine-layer structures cater to a broad market spectrum.

6. State-of-the-Art Production Facilities

• Five-Layer and Seven-Layer Co-Extrusion Lines: Precision gear pumps and automated gauge control for ±3 μm thickness uniformity.

• Six-Color Gravure/Flexo Printing: High-resolution imagery, metallic inks, and matte/gloss finishing options.

• Dry Lamination & Adhesive-Free Lamination: Enables solventless bonding, accelerating line speed to 120 m/min.

• Five Bag-Making & Two Slitting Lines: Custom shapes including D-cut, handle-punch, zipper pull, and hang-hole options.
