Customizable Flexible Octagonal Seal Bags

Overview

Specialized octagonal seal bags crafted from food-grade multi-layer composite materials (PET/AL/PE) through processes including film compounding, precision printing, and eight-side heat sealing. These bags integrate food contact safety, structural stability, and shelf display appeal. Suitable for packaging 50g to 2kg food such as snacks, nuts, dried fruits, and premium confectionery. They feature strong barrier properties, moisture resistance, and upright placement, widely applied in food processing enterprises, high-end supermarkets, and e-commerce retail scenarios.

Product Features

Food-Grade Multi-Layer Material: Complies with GB 4806.7-2016 standard, non-toxic, odorless, no substance leaching, safe for direct contact with solid, granular, and block foods.

Strong Freshness & Structural Retention: Eight-side full-sealing structure blocks oxygen, moisture, and light comprehensively, preventing food oxidation, dampness, and flavor loss; three-dimensional shape maintains upright stability, extending shelf life by 6-12 months.

Clear & Wear-Resistant Marking: High-adhesion eco-friendly ink printing, patterns and text are clear and fade-resistant even with friction. Customizable product information, shelf life, and corporate logos for easy traceability and brand promotion.

User-Friendly Design: Optional resealable zippers, tear notches, and transparent windows; eight-side structure distributes stress evenly, ensuring stable shelf placement, easy to open and seal repeatedly for consumer use and storage.

Product Advantages

Superior Barrier & Structural Performance: Oxygen transmission rate ≤2cc/(m²·24h·0.1MPa), moisture transmission rate ≤3g/(m²·24h); eight-side sealing strength ≥15N/15mm, not easy to deform or burst, better than ordinary flat bags.

Flexible Customization: Supports size (50g-2kg), color, material (transparent/opaque/metallized), and functional design (zipper/window) customization; blank bags available for emergency needs.

Cost-Effective & Display-Enhancing: Optimized production process reduces costs compared to rigid packaging; three-dimensional upright design enhances shelf visibility, boosting consumer purchase willingness; lightweight structure lowers logistics costs.

Wide Application Scope: Adaptable to packaging of solid (snacks, confectionery), granular (nuts, dried fruits), and block (jerky) foods, meeting diverse needs of snack, health food, and premium food brands.

Quality Assurance

Adheres to GB/T 10004-2008 and food contact standards, with multiple inspections per batch to ensure the following:

Barrier & Sealing Strength: Passes 72-hour high-humidity test with no food quality changes; heat-sealing strength ≥15N/15mm, no leakage under internal pressure of 0.2MPa, suitable for long-distance transportation.

Tear & Impact Resistance: Tear strength ≥50N, resistant to accidental puncturing; no bag damage when fully loaded (2kg) and dropped from 1.2 meters, ensuring transportation safety.

Printing & Hygiene Control: Printing color consistent, no smudges or blurring; material meets food hygiene requirements, no peculiar smell or harmful residue, suitable for direct food contact.

After-Sales Commitment: Free return and exchange provided with proof for quality issues (sealing failure, material peculiar smell, structural deformation) under normal use.
