Top 6 Biodegradable Film Blowing Machine Manufacturers for 2026

Quick answer: A biodegradable film blowing machine is a blown film extrusion line configured for specified biodegradable resin grades or blends, such as PLA and PBAT; compostability is a separate property verified on the finished film. Processing requirements depend on the resin grade, so the useful question for any builder is which named grades it has run and what the trial film showed. On PRM-Taiwan, JANDI'S documents dedicated PLA/PBAT models and KANG CHYAU documents die-head and component adjustments for PBAT, PLA, PS and PVA on their own websites; LUNG MENG and CHYI YANG list blown film lines under PRM-Taiwan's PLA/PBAT category and are worth a trial request. In Europe, Reifenhäuser's EVO Bio line is built for biopolymers and compostable film, and Windmöller & Hölscher's VAREX II lists PLA and biomaterials among its raw materials. Information checked as of 2026-09-21.

Converters considering PLA/PBAT film for carrier bags or mulch film need to match the line to the intended resin grade and film specification. A standard line can sometimes be adapted, but the screw, die and cooling package decide whether a given resin runs stably or tears at the bubble. This guide explains what to specify and lists the builders whose own product pages document biodegradable or compostable film capability.

What Is a Biodegradable Film Blowing Machine?

A biodegradable film blowing machine is a blown film extruder engineered or configured to process specified biodegradable resin grades or blends, such as PLA, PBAT and their blends, into tubular film for bags, mulch film and packaging. Compostability is a separate property that must be verified for the finished film under its intended disposal conditions. The architecture matches a conventional film blowing machine: extruder, annular die, inflated bubble, haul-off and winder. What differs is the process window, and that window depends on the resin grade and blend rather than on a single rule: ask the resin supplier and the machine builder to confirm drying, temperature, residence-time and bubble-stability requirements for the grade you will run. A machine designation alone establishes neither the resin formulation nor the certification of the film made on it.

Types of Lines for Compostable Film

Monolayer machines produce film with a single layer formulation.

Co-extrusion lines (A/B/A and above) allow different layer formulations in one film. Compare cost and film performance using the proposed layer structure, and confirm that the complete film, not only one layer, meets the requirements for its intended use and disposal route.

In-line converting systems join film blowing with printing and bag making in one pass. Confirm whether the proposed configuration has been demonstrated with your resin, and confirm line speed and tension settings using the intended resin and film thickness.

Laboratory machines cover resin trials before a production order; JANDI'S lists a TINY-25 lab machine for this purpose.

How to Choose a Biodegradable Film Blowing Machine

Start with the resin. Ask which PLA/PBAT grades the builder has run and request a trial report. Ask the builder to identify tested resin grades and provide trial results for the proposed configuration.

Ask for the adaptation list. Long residence time and high shear degrade PLA-based blends. Ask the builder to state which parts change for your resin: screw, die gap, temperature zones, cooling. KANG CHYAU, for example, states that it adjusts the die head and other components to the raw material.

Fix the film, then the width and layers. Decide the target film first, including thickness and the certification it must carry, and let it drive monolayer versus co-extrusion and the layflat width you actually need.

Plan for trim and start-up waste. If the builder also offers a film recycling system, ask whether it supports the specified resin and what regrind ratio has been validated while still meeting the film requirements. Regrind capability on polyethylene does not transfer automatically.

Ask for the trial protocol in writing. Named resin grade, film thickness and width, sustained output, trial duration and trial-film results are the items that make one builder's offer comparable with another's.

Ask whether the line reports energy per kilogram. Energy consumption per kilogram of film lets running cost on the intended resin be measured rather than estimated; ask what measurement the line provides.

How We Picked These Manufacturers

1. Blown film extrusion is the builder's core business, verified through its PRM-Taiwan showroom and, where reachable, its own website. Bag machine makers and material suppliers that only appear in the category listing were excluded.
2. Evidence of biodegradable capability, at one of two levels, stated for each builder. Level one: the builder's own website documents PLA/PBAT or biopolymer machines. Level two: the builder lists blown film lines under PRM-Taiwan's PLA/PBAT category and blown film extrusion is its core business. Level two identifies a supplier to investigate, not a verified capability, so those entries carry a trial requirement in the table.
3. Buyers can act on the listing: every Taiwanese manufacturer has a showroom and inquiry form on PRM-Taiwan; the two European builders are linked to the product pages we checked and are described only in the terms those pages use.

Limits. We did not run film on any of these machines and did not obtain comparable quotes, energy figures, warranty terms or service coverage. Output rates and widths are not compared because published figures are not measured on the same resin. Information checked as of 2026-09-21.

Frequently Asked Questions

Can a standard film blowing machine run PLA or PBAT?

It depends on the resin grade and the line. Some grades run on an adapted polyethylene line and some do not, so ask the builder which grades it has run and request trial-film results rather than a general assurance.

What is the difference between a film blowing machine and a biodegradable film blowing machine?

The layout is the same. A biodegradable film blowing machine is a blown film line whose screw, die head and cooling are specified for compostable resins, ideally proven on named PLA/PBAT grades with a trial report.

Does a biodegradable film blowing machine guarantee compostable film?

No. Compostability is certified on the finished film, which depends on the resin formulation, additives and thickness as well as the process. The machine is one input; the certification is a separate step with the resin supplier and a testing body.

Do Taiwanese manufacturers make biodegradable film blowing machines?

Yes. Fourteen suppliers list products under PRM-Taiwan's Biodegradable PLA/PBAT Blown film Machine category. This article covers those whose core business is blown film extrusion, and states for each whether its own website documents PLA/PBAT machines or whether the evidence is category placement that a trial has to confirm.

Monolayer or co-extrusion for compostable bags?

Monolayer film is common for carrier bags and mulch film; co-extrusion allows different layer formulations. Compare cost and film performance on the proposed structure and confirm the finished film meets the requirements for its intended use and disposal route; for mulch film, specify whether soil biodegradation is required.

Does PRM-Taiwan sell these machines directly?

No. Each manufacturer runs its own showroom and answers inquiries directly. Use the request-a-quote link on any Taiwanese builder above or the category page.

Find Your Compostable Film Line Partner

If you know your resin and target film, send the specification to two or three builders above and ask each for a trial report on your grade. If you are still weighing monolayer against co-extrusion, describe the end product, thickness and volume and let PRM-Taiwan route the inquiry to suitable Taiwanese manufacturers.
