QiuBao Classic Flavor Popcorn Flat‑Bottom Pearlized Bag / QiuBao Yearly Bestseller Spherical Popcorn Pearlized Flat‑Bottom Bag / QiuBao Pearlized Moisture‑Proof Flat‑Bottom Popcorn Food‑Grade Woven Bag

Product Introduction

Specialized packaging bags for spherical popcorn, designed for industrial-scale packaging of ball‑shaped or butterfly‑shaped popcorn. Featuring a food‑grade inner liner or laminated structure, these bags help preserve the popcorn’s crispiness and ensure hygienic safety during transportation and storage.

Applicable Subjects

Popcorn production facilities, snack food processing companies, snack brands, and export traders

Suitable for supplying bulk popcorn to channels such as supermarkets, convenience stores, movie theaters, and restaurant chains.

Product Positioning

Mid-to-high‑end snack packaging bags, designed to deliver superior moisture resistance, freshness preservation, and compression protection, are specially tailored for puffed and fragile snacks while balancing cost efficiency and shelf life.

Core Advantages

Moisture‑proof sealing: The inner liner or laminated layer effectively blocks moisture, keeping the popcorn crisp.

Compression and puncture resistance: High-strength woven base material, resistant to bag rupture during stacking.

Excellent printability: Color printing can showcase eye-catching brand graphics, enhancing shelf appeal.

Material and Craftsmanship

Typical structure (three-layer composite):

Outer layer: BOPP or pearlized film (for color printing)

Middle: PP woven fabric (provides strength)

Inner layer: PE or CPP heat-seal layer (food-contact grade, moisture-proof heat seal)

Process: Gravure color printing → Lamination → Bag making (three-side seal, back-seal, or gusseted bag)

Tensile strength (for woven substrates)

Woven fabric tensile load (warp/weft) ≥ 450 N/50 mm (in compliance with GB/T 8946)

Tensile strength of the finished bag: It can withstand 20–25 kg of contents without tearing when stacked in three layers.

Moisture-proof rating

Water vapor transmission rate (water vapor permeability) ≤ 15 g/(m²·24h) (according to ASTM E96 or GB/T 1037)

When used in conjunction with an internal desiccant or nitrogen‑flushed packaging, the shelf life can be further extended.

Packaging drop test

In accordance with GB/T 4857.5: After being filled to its nominal weight, the bag is dropped freely from a height of 1.2 m onto a cement floor; the bag shall show no rupture or leakage.

Applicable filling method

Suitable for vertical form-fill-seal (VFFS) machines or pre-made bag fillers, such as bag‑in‑box packaging machines.

Packaging Specifications

Net content: 20 kg ± 0.1 kg or 25 kg ± 0.1 kg (both specifications are shown in the image; the bag may be dual‑purpose, or the customer can choose).

Bag Types: Three-side-seal flat pouch / Folded-edge stand-up pouch / Pouch with handle (customized to customer requirements)

Finished bag dimensions: Designed according to the density of the contents; typical size is approximately 50 × 80 cm (for 25 kg).

Customization Scope

Bag type, dimensions, and thickness (typically 0.08–0.12 mm total composite thickness)
