Custom Ziplock Packaging – Product Overview
Product Overview Custom Ziplock Packaging, including zip-seal bags and bone-seal bags, are flexible plastic packaging products that can be manually sealed without heat-sealing equipment by pressing the integrated interlocking ribs at the bag opening. They are reusable, environmentally friendly general packaging consumables.
The products are made of LDPE, offering soft texture, high toughness, good tensile strength, moderate transparency, excellent low-temperature resistance, not easily brittle or whitening. They provide effective moisture, dust, and oxidation protection. These bags can be applied across industries, including food, daily chemicals, electronics, hardware, apparel, and gifts. Custom zip-seal bags offer core advantages such as easy opening and closing, strong sealing, reusability, excellent storage, high print compatibility, and flexible customization. They comply with SGS, FDA, and EU food contact regulations and meet import security standards of various countries.
ziplock bags Styles
- Standard Flat Zip-Seal Bags: Classic basic style with a flat body, no gussets, simple structure, high cost-performance ratio. Widely used in export wholesale for small item storage, portioning, and dust/moisture-proof packaging.
