High-Quality LDPE Flat Bags | Custom Size & Thickness for Packaging

Product Overview

Our LDPE Flat Bags (Low-Density Polyethylene Flat Pouches) are a versatile packaging solution designed for industries ranging from food service to retail and industrial manufacturing. Manufactured using premium-grade virgin or recycled materials, these bags offer exceptional clarity, flexibility, and sealing strength.

As a specialized packaging manufacturer, we provide custom sizes, thicknesses, and printing options to meet the specific needs of your business.

What Are LDPE Flat Bags?

LDPE flat bags are non-gusseted, open-top bags made from Low-Density Polyethylene film. Unlike ziplock or self-adhesive bags, flat bags are simple, cost-effective, and ideal for high-speed manual or automatic packaging lines.

They are widely used as:

• Inner liners for cartons or woven bags

• Food packaging (bread, produce, frozen items)

• Retail packaging (clothing, hardware, stationery)

• Industrial protective covers

Key Features & Benefits

1. Food-Grade & Safe

Our LDPE flat bags are manufactured in a clean environment and are compliant with FDA and EU food contact standards. They are odorless, non-toxic, and safe for direct contact with dry and frozen food products.

2. High Transparency & Presentation

With excellent optical clarity, our bags allow your product to be fully visible, enhancing shelf appeal for retail and e-commerce applications.

3. Customizable Thickness (Gauge)

We offer a wide range of thicknesses from 0.02mm to 0.12mm (20μ to 120μ / 2 to 12 mils) .

• Thin gauge (20-40μ): Ideal for lightweight items like bread, herbs, or small parts.

• Medium gauge (50-80μ): Suitable for frozen food, clothing, or hardware.

• Heavy gauge (90-120μ): Used for industrial parts, tools, or heavy-duty liners.

4. Excellent Heat Sealability

LDPE material offers a wide heat-sealing range, ensuring strong, leak-proof seals on both manual impulse sealers and high-speed automatic packaging machines (HFFS/VFFS).

5. Custom Printing Available

We support gravure printing with up to 8 colors. Your logo, barcode, and product information can be printed clearly and durably on the bag surface.
