The production of high-quality self seal craft bags involves a meticulously controlled, multi-stage manufacturing process, ensuring material integrity, precise sealing capabilities, and consistent product dimensions. Our facilities adhere strictly to ISO 9001 quality management standards and employ advanced polymer extrusion and conversion technologies.
Product Materials: Typically crafted from high-grade virgin LDPE (low-density polyethylene) or HDPE (high-density polyethylene) for flexibility and strength, or PP (polypropylene) for enhanced clarity and rigidity. Food-grade options use materials compliant with FDA 21 CFR 177.1520 regulations.
Service Life: With proper storage and use, these bags offer a service life of 2-5 years, maintaining their structural integrity and adhesive efficacy. Factors like UV exposure, extreme temperatures, and chemical contact can influence longevity.
Target Industries: These versatile bags find extensive use in packaging for retail & e-commerce, arts & crafts, textile & apparel, food service, medical & pharmaceutical, and component manufacturing industries.
Advantages in Typical Application Scenarios: In e-commerce fulfillment, the self-sealing mechanism significantly reduces packaging time and labor costs, leading to energy savings by streamlining operations. For medical device packaging, the sterile environment maintained by an effective seal and barrier properties ensures product safety, while their corrosion resistance protects sensitive components from environmental degradation. The clarity of clear plastic self sealing bags is crucial for quality control inspections without opening the package.

| Film Thickness | 2.0 mil - 6.0 mil (50-150 microns) | ASTM D374 (Thickness) |
| Tensile Strength | ≥ 20 MPa (MD), ≥ 18 MPa (TD) | ASTM D882 |
| Tear Resistance (Elmendorf) | ≥ 150 gf/mil | ASTM D1922 |
| Puncture Resistance | ≥ 20 N | ASTM D3763 |
| Seal Strength (Self-Adhesive) | ≥ 0.5 N/mm | ASTM F88 |
| Oxygen Transmission Rate (OTR) | 200-500 cc/m²/day (at 23°C, 0% RH) | ASTM D3985 |
| Moisture Vapor Transmission Rate (MVTR) | 5-15 g/m²/day (at 38°C, 90% RH) | ASTM F1249 |
| Temperature Resistance | -40°C to +80°C (operational) | Internal Thermal Cycling |
| Food Contact Compliance | FDA 21 CFR 177.1520 (for relevant grades) | FDA Regulations |
Understanding these parameters is crucial for selecting the appropriate self seal craft bags for specific applications, ensuring optimal product protection and compliance with industry standards. For instance, low OTR and MVTR values are critical for extending the shelf life of perishable goods within self sealing bags for food.
