Gallon Quart Food Bags Manufacturers, Suppliers, Factory

1. Brief Introduction:

(1) Key Advantages

Gallon & Quart Food Bags are resealable food-grade plastic storage bags designed for food storage, portion control, and reducing kitchen waste — widely used across supermarket, retail, and foodservice channels.
Reliable seal, leak-free storage: Available in single-zipper, double-zipper, and slider closure designs that are leak-proof and moisture-resistant, eliminating common operational pain points such as seal failures, leakage during transport, and freezer burn — reducing customer complaints and returns.
Food-grade safety + freezer-grade durability: Made from food-grade LDPE/LLDPE material, BPA-free, customizable thickness (standard or heavy-duty freezer grade), flexible and puncture-resistant, suitable for refrigeration, freezing, and repeated use.
Fully customizable: Any size, thickness, color, and packaging quantity available.

(2) Applicable Scenarios

Kitchen / Freezer / Meal Prep / Bulk Marinating / Dry Storage / Portion Control

(3) Target Audience / Channels

Supermarket buyers, retail grocery distributors, foodservice operators (restaurant chains / central kitchens), private-label buyers, and household consumers for everyday kitchen storage needs.

(4) Slider Type

Slider closure (Gallon size only)

(5) Closure Type

Press-to-Seal (standard, available in single-zipper and double-zipper)
Slider (premium upgrade, Gallon size only)

(6) Seal Integrity

Single-zipper seals are suitable for everyday dry goods and light household use. Double-zipper seals add a second interlocking zipper channel for a more secure close, better suited to liquids or moist ingredients, effectively reducing the risk of accidental opening and leakage. 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: The double-zipper design provides stronger leak protection for marinades, sauces, and other liquid ingredients.
Moisture resistance: Freezer-grade film at 2.7 mil or above offers better crack and puncture resistance at low temperatures, effectively blocking moisture and condensation.
Airtightness test data: Available on request.

(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 product quality tier, directly impacting user experience and packaging reusability in high-frequency meal-prep and commercial applications.

(9) The Number of Times a Zipper Can Be Reused Reflects the Quality and Grade of the Product

Standard press-to-seal (single-zipper): suitable for everyday dry goods, moderate reuse frequency
Double-zipper press-to-seal: ≥80–100 times, well suited to frequent refrigeration/freezing access
Slider closure (Gallon, premium): delivers a more consistent seal under frequent open/close use, showing slower seal-strength degradation than comparably priced press-to-seal-only bags

2. Basic Specifications

Film thickness is available in two grades, standard storage (1.0–2.5 mil) and heavy-duty freezer (1.8–2.5 mil), so buyers can choose based on use case and budget. Size, color, and packaging quantity can all be customized per order.

4. Product Physical Properties

At Huayue, we lab-test every film we produce for tensile strength, tensile strength at break, elongation at break, impact resistance, and seam strength — so the numbers you see here aren't theoretical, they're what we measure in our own facility. We share this data with buyers as a real reference point for evaluating durability and seal reliability, and if you have specific requirements around tensile strength or any other property, we're happy to run customized testing and provide the corresponding test reports.

Physical Properties (Factory Laboratory Test Data)
