Stand Up Double Zipper Freezer Bags Bulk | Packaging Bags Supplier

Product Overview

Haidapack’s Full-Gusset Stand-Up Double Zipper Freezer Bags redefine structural efficiency in modern food preservation and home organization. Moving away from traditional flat-profile bags that collapse under weight, this specialized collection introduces an integrated expandable bottom gusset across all available sizes (S, M, and L). The wide-crease foundation allows every bag to stand completely upright independently once filled, creating a seamless, hands-free station for liquid pouring and ingredients batching.

Engineered with a finely balanced 0.05mm flexible high-density Polyethylene (PE) profile, these bags combine strong puncture resistance with premium tactile pliability. This specific thickness allows users to easily press out excess air before locking, optimizing vacuum sealing and successfully defending fresh foods from moisture loss, dust, and freezer burn. Packed into standard boutique-slender boxes (25, 15, and 10-count), this series is optimized for top-tier retail chains and grocery store networks looking to supply reliable, space-saving kitchen essentials.

Core Product Differences (Compared to the Previous Series)

• Full-Series Three-Dimensional Bottom Gusset: Unlike standard storage lines, this series scales up its expandable bottom base from 60mm up to 80mm for the large capacity size. The stand-up structure transforms your refrigerator and cabinet spaces, turning floppy bags into highly organized vertical storage rows.

• 0.05mm High-Flexibility Polymer Membrane: Calibrated at a flexible 0.05mm thickness, providing an ideal mid-range balance between structural weight load limits and soft sealing flexibility. It makes compressing, folding, and purging air entirely effortless.

• Multi-Purpose Household & Office Utility: Optimized for universal tasks. Beyond cold food storage, the dustproof and moisture-proof upright construction makes it highly reliable for storing electronics, hardware components, clothing accessories, and cosmetics.

Key Features & Benefits

• Reinforced Double Zipper Lock Track: Features dual parallel sealing rib bands that interlock perfectly. It seals out external air, traps inner moisture, and entirely eliminates messy spills or cross-contamination.

• Hands-Free Filling & Prep Experience: The self-standing flat bottom stabilizes the container rim, enabling one-handed food placement without the risk of the bag tipping over and spilling liquid contents.

• Smudge-Proof Date Labeling Block: Equipped with a matte-surface texture box that accepts standard ballpoint or ink markers easily, helping users track food production dates and expiration times with ease.
