2. Product Focus: Vacuum Seal Food Packaging Solutions  

Vacuum sealing is essential for maintaining food quality, preventing spoilage, and ensuring product safety during transportation and storage. Our high-barrier vacuum packaging films are designed to meet diverse industry needs, from frozen foods to retort-ready meals. Below, we detail our specialized solutions for vacuum-sealed food packaging:  

---

#2.1 High-Temperature Deep-Drawn Film (HT Series)  

Applications: Ideal for foods requiring high-temperature sterilization (121°C), such as ready-to-eat meals, soups, and meat products.  

Key Features:  

- Unmatched Barrier Properties: Oxygen Transmission Rate (OTR) ≤ 3 cm³/m²·24h·atm; Water Vapor Transmission Rate (WVTR) ≤ 5 g/m²·24h.  

- Heat Resistance: Withstands retort sterilization at 121°C for 60 minutes without delamination or seal weakening.  

- Puncture Resistance: Tensile strength ≥ 45 MPa (machine direction) and ≥ 40 MPa (cross direction); elongation at break ≥ 400%.  

- Deep-Draw Compatibility: Supports forming depths up to 25 mm, ensuring airtight sealing around irregular food shapes.  

Material Structure:  

- 5-Layer Co-Extruded Film: PA (Nylon)/EVOH (Ethylene Vinyl Alcohol)/PE (Polyethylene)/Adhesive/PP (Polypropylene).  

- Thickness Range: 80–200 microns (customizable based on client requirements).  

Benefits for Food Packaging:  

- Extends shelf life to 12–18 months under refrigeration.  

- Maintains vacuum integrity during sterilization, transportation, and storage.  

- Resists lipid oxidation, microbial growth, and flavor loss.

#2.2 Low-Temperature Deep-Drawn Film (LT Series)  

Applications: Perfect for frozen foods, chilled meats, and products requiring pasteurization (up to 100°C).  

Key Features:  

- High Clarity & Gloss: Enhances product visibility for retail appeal.  

- Flexibility at Low Temperatures: Retains elasticity even at -40°C, preventing cracks during freeze-thaw cycles.  

- Strong Barrier Performance: OTR ≤ 5 cm³/m²·24h·atm; WVTR ≤ 8 g/m²·24h.  

Material Structure:  

- 5-Layer Co-Extruded Film: PET (Polyester)/PE/EVOH/Adhesive/PA.  

- Thickness Range: 60–150 microns.  

Benefits for Food Packaging:  

- Preserves texture and moisture in frozen and chilled foods.  

- Resists grease and oil penetration, ideal for fatty meats and dairy products.

#2.3 Multi-Layer High-Barrier Stand-Up Pouches  

Applications: Coffee, snacks, dried fruits, and powdered foods.  

Key Features:  

- 9-Layer Structure: PET/AL (Aluminum Foil)/NY/PE/Adhesive/EVOH/PP.  

- Lightweight & Durable: Thickness 120–250 microns; tear resistance ≥ 8 N.  

- Resealable Zippers: Optional zip-lock features for convenience.  

Benefits:  

- Blocks UV light, oxygen, and moisture to preserve flavor and aroma.  

- Compatible with vertical form-fill-seal (VFFS) machines.
