2. Product Focus: Vacuum Pack Bags  

Vacuum pack bags are critical for preserving food freshness, preventing oxidation, and extending shelf life. Our high-barrier vacuum bags are engineered to withstand extreme temperatures, mechanical stress, and sterilization processes while maintaining superior vacuum integrity. Below, we detail our specialized vacuum pack bag solutions:  

---

#2.1 High-Temperature Vacuum Bags (HT Series)  

Applications: Ideal for cooked meats, sausages, and ready-to-eat meals requiring retort sterilization (121°C).

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

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

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

- Deep-Draw Compatibility: Supports forming depths up to 25 mm for snug packaging around irregularly shaped products.  

Material Structure:  

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

- Thickness: 80–200 microns (customizable).  

Benefits:  

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

- Maintains vacuum integrity during high-temperature processing and transportation.

- Thickness: 60–150 microns.  

Benefits:  

- Preserves texture and moisture in frozen and chilled foods.  

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

---

#2.3 Multi-Chamber Vacuum Bags  

Applications: Portion-controlled packaging for sliced meats, cheeses, and snacks.  

Key Features:  

- Pre-Scored Chambers: Easy-to-tear compartments for single servings.  

- High Seal Strength: ≥ 10 N/15mm to prevent leaks.  

- Anti-Fog Coating: Optional inner layer to maintain product visibility.  

Material Structure:  

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

- Thickness: 120–250 microns.  

Benefits:  

- Reduces food waste by enabling controlled portioning.  

- Compatible with vertical and horizontal form-fill-seal machines.
