Garbage Bags

Garbage bags are the most volume-driven product in flexible packaging: drawstring bags on rolls, flat bin liners and printed retail packs.

How the line works

Producing for Garbage Bags — the short answer

Garbage bag film splits into two families. Retail point-of-sale bags use thin, stiff HDPE at 0.008–0.02 mm — run on a monolayer HDPE line from 0.008 mm upward. Kitchen catchers and heavy-duty sacks use soft LDPE/LLDPE blends at 0.03–0.08 mm, where an ABA co-extrusion line lets you carry recycled material in the core layer without losing seal strength.

A working line at 80 kg/h produces roughly 1.6 t of film per 20-hour day — on 0.015 mm stock, on the order of 500,000 bags. Downstream, a dedicated garbage bag making machine folds, seals and star-seals or draws the string in one pass.

Frequently asked questions

01

What film is best for garbage bags — HDPE or LDPE?

HDPE for thin, stiff retail bags down to 0.008 mm; LDPE/LLDPE for soft, puncture-resistant sacks at 0.03–0.08 mm. An ABA co-extrusion line covers both directions and lets you blend recycled pellets into the core layer.

02

Which machine makes the star seal and drawstring?

A dedicated garbage bag making machine — such as the E-SHION DR — folds the gusset, heat-seals the star bottom and hot-welds the drawstring band in one continuous pass.

03

How many garbage bags can one line produce per day?

At a working 80 kg/h of 0.015 mm film, expect on the order of 400,000–500,000 bags per 20-hour day from the film line; the bag machine then sets the final count by its cycle rate and lane count.

04

Can I use recycled pellets in garbage bag film?

Yes — garbage bags are the classic non-food application. Reclaimed pellets are typically blended at 10–30% in the middle layer of an ABA structure, keeping virgin material on the sealing skins.
