Sandwich Bags Manufacturers, Suppliers, Factory

1. Brief Introduction

(1)Key Advantages

Sandwich bags are resealable food-grade plastic bags designed for storing sandwiches, snacks, deli items, baked goods, and meal-prep portions. They are also suitable for food delivery and retail packaging.
Reliable seal, leak-free transport: Available in single or double zipper designs (single zipper / double zipper) that are leak-proof and moisture-resistant, eliminating common operational pain points such as seal failures, bag fogging, and size mismatches — reducing customer complaints and returns.
Food-grade safety + extra-thick durability: Food-grade PE material, BPA-free, customizable thickness, sharp print quality, suitable for refrigeration and repeated use.
Fully customizable: Any size, thickness, and design available.

(2)Applicable Scenarios

Kitchen /Freezer / Travel / Snack / Meal Prep / Food and Beverage Services / Retail Packaging

(3)Target Audience / Channels

Food manufacturers, restaurant chains (fast food, coffee shops, bakeries), supermarket retailers, wholesalers, importers, e-commerce sellers (custom-branded packaging), and eco-conscious brands.

(4)Slider Type

Double zipper
Single zipper

(5)Closure Type

Press‑to‑Seal

(6)Seal Integrity

Barrier properties against gases and liquids.Good sealing performance = leak-proof + moisture-proof + freshness preservation + prevention of accidental opening during transport.

(7)Leak-proof/moisture-proof rating; availability of airtightness test data

Leak-proof: Suitable for packaging moist foods or small amounts of liquid without leakage during transport.
Moisture resistance: Uses thickened or high-barrier materials to effectively block water vapor.
Airtightness test data: Test reports available for negative pressure (bubble method) or positive pressure burst testing.

(8)Cycle Life

The number of times a zipper can be repeatedly opened and closed while maintaining an effective seal. This is a key indicator of zipper quality that directly impacts user experience and packaging reusability in high-frequency commercial applications.

(9)The number of times a zipper can be reused reflects the quality and grade of the product.

Standard press-type zipper: ≥50 cycles
Double zipper / single zipper ：≥80～100 times
