Large HDPE & LDPE Plastic Bags — Made In-House on Our Own Large-Format Machine

Many businesses need plastic bags or sheeting larger than what a typical supplier keeps in stock — machinery covers, pallet covers, or sheeting for construction sites. Most factories can only produce standard sizes, because their blown film machines simply can't handle that width. This article covers how large our HDPE and LDPE bags can go, what they're used for, and why having a genuine large-format machine in-house matters.

How Large Can HDPE & LDPE Bags Go?

GPS manufactures plastic bags from as small as 5 inches up to an oversized 150 inches, all on our own in-house machinery. Beyond finished bags, we also produce oversized plastic rolls starting from 1.5 meters wide, which customers can cut to size themselves on-site — ideal for jobs where standard finished bags simply aren't big enough.

One key thing to know: anything wider than 69 inches requires a dedicated large-format blown film machine. Standard blown film machines can't reach that width, which is exactly why most factories either turn down orders at this size or have to subcontract them out to another manufacturer.

Our Large-Format Machine's Production Capacity

Our large-format blown film machine runs at roughly 3,000 kilograms per day — about 10,000 kilograms per month. It can blow film as thin as 0.03 mm per side, and it's also capable of producing food-grade LDPE A and HDPE A bags. That covers both oversized jobs that need extra-thin film and applications that require direct food contact.

What Are Large HDPE & LDPE Bags Used For?

• Machinery and equipment covers — protection from dust and moisture during storage or transport

• Pallet covers — for warehouses and logistics operations that need to wrap large volumes of goods at once

• Construction — ground sheeting, or covering materials from rain and sun

• Large industrial waste bags — for factories or job sites generating more waste per cycle than a standard bag can hold

• Agriculture and warehousing — covering large stockpiles of produce or raw materials

Should You Choose HDPE or LDPE?

The logic for choosing resin doesn't change much at large sizes. HDPE offers higher mechanical strength, suited to jobs that need to bear weight or tension — like a pallet cover that gets strapped down. LDPE is more flexible and stretchy, better for jobs that need to be pulled over uneven or irregular surfaces — like covering oddly shaped machinery or a pile of construction material. If you're not sure which resin fits your job, our team can help based on your actual use case.

Why Order From a Factory With Its Own Large-Format Machine

Large HDPE and LDPE bags require a blown film machine specifically built for that width. Factories without one usually have to subcontract the job out, which drives up the price and makes it much harder to control quality or delivery timelines. GPS owns and operates its large-format machine in-house — from film blowing through to cutting and sealing — so we can guarantee quality control and delivery timelines far more reliably.

For large made-to-order runs, customers take on all production offcuts, and the final delivered quantity may run about 10% over or under the ordered amount, per standard manufacturing practice. We recommend specifying size, thickness, and quantity up front so our team can quote accurately.

Frequently Asked Questions — Large HDPE & LDPE Plastic Bags

What's the largest size you can produce? From 5 inches up to 150 inches, plus oversized plastic rolls starting from 1.5 meters wide.

Why do some factories refuse orders wider than 69 inches? Because anything past 69 inches requires a dedicated large-format blown film machine, which not every factory has. GPS owns this machine in-house, so we can take on this size without subcontracting.

Is there a minimum order for oversized sizes? Yes, it depends on the size ordered. Send us your spec and quantity and our team will confirm pricing and the minimum order quantity.

For custom production runs, why doesn't the delivered quantity match the order exactly? This is standard for made-to-order manufacturing — customers take on all production offcuts, and the final quantity may run about 10% over or under what was ordered.

Should I choose HDPE or LDPE for a large cover? It depends on the job. Choose HDPE if it needs to bear weight or tension; choose LDPE if it needs flexibility to cover an uneven surface. Tell our team your actual use case and we'll help you pick the right resin.

How much can your large-format machine produce per month? Roughly 3,000 kg per day, or about 10,000 kg per month.

What's the thinnest film you can blow? As thin as 0.03 mm per side.

Can bags from this machine be used for food? Yes — our large-format machine is capable of producing food-grade LDPE A and HDPE A bags, which are safe for direct food contact.
