Garbage Bag Making Machine: Perforated Roll Bag Guide

Garbage bags are consumed nonstop by homes, hospitals, hotels and factories, and demand never really stops. That makes bin liner production one of the most popular entry points into the plastic bag business. A garbage bag making machine is usually a perforated roll bag machine: the film is bottom-sealed, a tear line is perforated between bags and the product is wound onto a roll. This guide explains how it works, which products it can make and what to check before you buy.

How a perforated roll bag machine works

1. Film feeding: Flat or gusseted tubular film from a blown film line is loaded onto the unwinder.
2. Folding (optional): The film can be folded lengthwise for a more compact roll.
3. Bottom sealing: The sealing bar welds the bag bottom at the set pitch.
4. Perforation: A serrated blade creates an easy-tear line right next to the seal.
5. Rewinding: Bags are wound automatically into rolls of a set count, such as 10, 20 or 30, with or without a core.
6. Tail sealing / labelling: The roll end is secured and the roll is ready for packing.

Servo-controlled feeding keeps bag length constant, while an automatic rewinder changes rolls without stopping the line. See full details on our perforated roll bag machines page.

Which garbage bags can you make?

Standard household roll bags

Thin bags, roughly 8–20 microns, usually from HDPE or recycled-blend film and sold on rolls. This is the best-selling supermarket segment.

Gusseted and drawstring bin liners

Gusseted tubular film gives higher-volume bags. Drawstring bags have a tape threaded through the mouth, which needs an additional tape feeding and sealing unit.

Industrial and jumbo refuse sacks

Large, thick bags (typically 30–100 microns) in LDPE/LLDPE for municipalities, hospitals, factories and hotels. Thick film needs a wide, powerful sealing bar. In this segment, individually cut and folded sacks from a bottom seal bag machine are also common.

Freezer bags and food bags on roll

Thin, food-grade LDPE or HDPE bags sold on rolls or in boxes, made with the same perforated roll principle in smaller sizes. Resin choice and hygiene in the production area need extra care.

Raw material for garbage bags

Garbage bags are one of the best outlets for recycled resin. Turning your own trim, rejects or purchased post-consumer film into pellets with a plastic recycling machine and blending it with virgin resin cuts material cost significantly. As the recycled share goes up, film strength and sealing behaviour change, so the blend ratio should be tested against the target gauge and strength.

What to check when choosing a machine

• Working width: Size it to your widest bag; 400–1200 mm is a common range for bin liners.
• Sealing bar: If you will run both thin and thick film, temperature and dwell time must be adjustable over a wide range.
• Rewinder: Core/coreless winding, automatic roll change and counting determine real output.
• Folding unit: Reduces roll diameter and simplifies packing.
• Perforation blade: Must balance easy tearing against the roll breaking on its own.
• Service and spares: Fast access to knives, PTFE tape and heaters matters.

The full garbage bag production line

You can start with a roll bag machine alone and buy film on rolls. For a lasting cost advantage, most producers build a line: film extrusion on a blown film machine → sealing, perforating and winding on a perforated roll bag machine → scrap reprocessing on a recycling machine. We cover every step in our guide on how to start a plastic bag factory.
