Applications
This versatile bag size suits a wide range of B2B packaging needs across multiple industries. In food service and specialty food operations, use these bags for portioning baked goods, candy, nuts, spices, tea samples, and condiment packets. The 4 mil thickness provides adequate moisture barrier protection while maintaining clarity for product visibility.
Manufacturing and distribution facilities rely on these bags for organizing hardware components including screws, bolts, washers, small electrical parts, and replacement components. The puncture-resistant 4 mil gauge protects against sharp edges while the clear film allows for easy identification and barcode scanning without opening packages.
Retail and e-commerce operations use these bags for jewelry packaging, cosmetic samples, craft supplies, refill packs, and product inserts. The professional appearance and FDA compliance make them suitable for direct-to-consumer applications where presentation and safety matter.
Key Features
- 4 mil heavy-duty thickness - Provides superior puncture resistance and durability compared to 1.5-2 mil commodity bags, protecting contents during handling and transit
- Heat-sealable - Compatible with standard heat-sealing equipment for tamper-evident closure; can also be closed with twist ties, bag tape, or staples
- Excellent clarity - Virgin LDPE resin provides optical clarity for product inspection, label readability, and professional presentation
- Moisture and dust protection - Polyethylene film creates effective barrier against environmental contaminants, maintaining product freshness and cleanliness
- Open-end design - Allows fast loading in high-volume packing operations without specialized equipment
- Case quantities - 1,000-count cartons reduce reorder frequency and storage handling in commercial facilities
Why 4 Mil Thickness
The 4 mil gauge represents the optimal balance for general industrial use. It is significantly stronger than light-duty 1.5 mil bags used for dust covers, yet more economical than 6 mil extra-heavy bags reserved for extreme-duty applications. This thickness handles most commercial packaging tasks including moderately sharp parts, frozen food items, and retail products requiring professional presentation.
