Common questions
What closure method works best with these 14 x 20" poly bags?
These bags feature an open-end design compatible with multiple closure options: twist ties for quick sealing, bag tape for secure permanent closure, or impulse sealers for high-volume industrial operations. Choose based on your workflow and frequency of use.
Are these bags food-safe and compliant with regulations?
Yes. These 4 mil polyethylene bags meet FDA and USDA specifications, making them suitable for food storage, meal prep, and institutional food service applications while maintaining compliance across all 50 states.
What makes 4 mil thickness the right choice for heavy products?
4 mil polyethylene provides excellent puncture and tear resistance for tools and hardware while maintaining cost-efficiency. This thickness balances durability with material economy, thicker bags increase cost without proportional durability gains for most industrial applications.
How many bags do I need per case, and what's the cost per unit?
Each case contains 500 bags, delivering significant per-unit savings compared to smaller quantities. Bulk case purchases are ideal for businesses with consistent packaging needs and provide 20-30% better unit economics than retail packaging options.
