Frequently Asked Questions About Industrial Zipper & Ziplock Bags
Can we co-load heavy cartons of zipper bags with bulky rigid drum liners in the same container?
Yes—this is one of Lucheng’s core cost-saving advantages for importers and distributors. Zipper and slider bags are high-density dead-weight cargo, whereas rigid drum liners are lightweight volumetric cargo. Co-loading both in a 40’HQ container maximizes both weight and volume limits, saving 35% to 50% on ocean freight per unit.
What thickness and closure options do you manufacture for industrial hardware vs. food storage?
We extrude and convert from 2.0 Mil (50 microns) up to heavy-duty 8.0 Mil (200 microns) puncture-resistant virgin LDPE. We offer single-track and double-track press-to-close reclosable zippers, write-on white block bags, hang-hole retail bags, ESD pink anti-static ziplock bags, and heavy-duty slider zipper bags.
Are your Ziplock and Slider bags certified for food contact and Amazon FBA / retail compliance?
Yes. All food and retail bags are blown from 100% virgin food-grade LDPE resin (zero recycled odor or plasticizer migration), 100% BPA-free, RoHS certified by Pony Testing, and available with multi-language suffocation warning printing and custom UPC/EAN barcodes.
