Custom Poly Bags & Corrugated Sheets for Industrial, Food, and Export Packaging Across India

What is the minimum gauge poly bag I should use for packaging goods above 5 kg?

A: For products weighing 5-15 kg, a minimum 150 micron LDPE poly bag is recommended; for 15-30 kg products, 200-300 micron or HDPE woven bags are appropriate — bag gauge should always be validated with a drop test on the filled bag.

Are food-grade poly bags required for indirect food contact applications?

A: For direct food contact (food touching the bag interior), FDA 21 CFR / FSSAI compliant food-grade bags are mandatory; for indirect contact (food in secondary packaging), standard bags may be used, but food-grade is always recommended to eliminate compliance risk.

What corrugated sheet ECT should I specify for pallet layer pads?

A: For pallet layer pads supporting up to 200 kg distributed load, ECT 400-600 N/m 3-ply board is sufficient; for heavy goods or multi-pallet stacking above 500 kg, 5-ply ECT 800-1,200 N/m double-wall sheets are recommended.

Can poly bags be custom printed?

A: Yes — most Trade4Asia verified poly bag suppliers offer 2-6 colour flexo printing with a minimum order of 500-2,000 units per design; custom print plates are typically ₹2,000-8,000 per colour one-time tooling cost.

What is the difference between LDPE and HDPE poly bags?

A: LDPE (Low Density Polyethylene) bags are soft, flexible, and transparent — ideal for general merchandise and food packaging; HDPE bags are stiffer, stronger, and more chemical-resistant — used for heavier goods, chemicals, and grocery carry bags.
