1. Non-woven Bags
Non-woven bags are made from synthetic fibers (usually polypropylene, PP) bonded together without weaving or knitting. They are lightweight, durable, and reusable. Features include breathability, resistance to tearing, and washability. Commonly used for shopping, promotional purposes, and packaging. Advantages: eco-friendly (recyclable and reusable), cost-effective, and customizable. Disadvantages: less waterproof than plastic bags and may lose shape over time.
2. PVC Bags
PVC (Polyvinyl Chloride) bags are made from a flexible plastic material. They are waterproof, durable, and often transparent or customizable with prints. Uses include fashion accessories, gift wrapping, advertising, and storage. Advantages: strong, affordable, and versatile. Disadvantages: not biodegradable, may release harmful chemicals during production or disposal, and limited recycling options.
3. PE Bags
PE (Polyethylene) bags are made from ethylene polymers. They are lightweight, flexible, and waterproof. Common types include LDPE (Low-Density) for plastic shopping bags and HDPE (High-Density) for thicker bags like garbage bags. Advantages: low cost, high durability, and moisture resistance. Disadvantages: non-biodegradable, contribute to plastic pollution, and require centuries to decompose in landfills.
These materials vary in environmental impact, cost, and functionality, making them suitable for different applications based on user priorities.
I. PVC Bag Manufacturing Process
Core Advantages: With 15 years of plastic packaging R&D experience, Qingdao Betfis Electric Appliances uses German imported extruders and Japanese printing equipment to support high-transparency and complex pattern customization.
1. Raw Material Selection
- Base Material: Polyvinyl chloride (PVC) resin (compliant with EU REACH regulations, phthalate content <0.1%).
- Additives: Eco-friendly plasticizer (DINP), stabilizer (calcium-zinc composite system), UV absorber (for outdoor weather resistance).
- Custom Options: Bio-based PVC (30% renewable content) available for Nordic zero-waste policies.
2. Production Flow
1. Extrusion Molding
- Twin-screw extruder melts materials into uniform sheets (thickness ±0.01mm).
- Cooling rollers ensure smooth, defect-free surfaces.
2. Printing
- 8-color gravure printing for high-resolution patterns (Pantone matching available).
- Special techniques: Heat transfer for gradients or UV printing for enhanced adhesion.
3. Cutting & Welding
- CNC cutting with ±0.5mm precision, smooth edges.
- Ultrasonic welding for medical-grade electronics packaging (e.g., humidifier parts), achieving IPX7-level sealing.
4. Post-treatment
- Matte/embossed finishes for premium texture (e.g., appliance gift bags).
- Vacuum aluminizing for metallic luster in high-end electronics packaging.
3. Quality Control
- Batch testing: Tensile strength ≥25MPa, elongation at break ≥200%.
- Sealing test: 2kPa pressure maintained for 5 minutes.
- Certifications: SGS-tested, RoHS compliant.
II. Non-woven Bag Manufacturing Process
Core Advantages: Equipped with Taiwanese high-speed non-woven production lines, supporting 50-200g/m² weight customization and 5 million units/month capacity.
1. Raw Material Selection
- Base Material: Polypropylene (PP) non-woven fabric (GB/T 24252 compliant).
- Eco-Upgrades: PLA masterbatch (15-30%) for 6-month compostable degradation.
- Special Treatments: PE lamination for 3000mm water column waterproofing.
2. Production Flow
1. Cutting
- Computer-aided nesting reduces material waste to <5%.
2. Sewing
- Multi-needle chain stitching (8-12 stitches/inch), reinforced handles (20kg load capacity).
3. Printing & Functionality
- Silk screen (fluorescent colors) or digital direct printing.
- Custom features: Built-in RFID shielding for EMI protection.
4. Finishing
- High-temperature setting for wrinkle-free results, automatic folding (gift-box style available).
3. Quality Control
- Sampling: Seam strength ≥80N/5cm, colorfastness ≥4 (ISO 105-B02).
- Waterproof test: 10-minute spray resistance.
- Certifications: (direct skin contact).
III. PE Bag Manufacturing Process
Core Advantages: Italian fully automatic blown film machines support 0.01-0.2mm thickness customization for precision electronics.
1. Raw Material Selection
- Base Material: LLDPE + LDPE blend (FDA food-grade compliant).
- Functional Additives: Antistatic agents (surface resistivity ≤10^9Ω) for electronics packaging.
- Eco-Upgrades: Starch-based degradable PE (12-18 month degradation).
2. Production Flow
1. Blown Film
- 3-layer co-extrusion for high transparency (haze <3%), ±3% thickness uniformity.
2. Bag Forming
- 3-side/center seal machines with heat-seal strength ≥15N/15mm.
- Custom features: Zipper bags, perforated breathable bags for motor cooling.
3. Printing & Inspection
- Flexo printing for appliance logo customization.
- Online defect detection (0.1mm² precision).
3. Quality Control
- Physical tests: Puncture strength ≥40N, dart impact ≥100g.
- Sealing test: -0.08MPa vacuum maintained for 30 seconds.
- Certifications: UL 2335 compliant (electronics packaging).
