Automatic Corn Starch Bag Making Machine for Biodegradable Bags

Many buyers now ask for compostable packaging, and converters need machines that can handle new film types. A corn starch bag making machine converts biodegradable film rolls into finished bags that are ready for filling, printing or retail.

Xinghong designs and builds automatic pouch machines in Jiangyin, China. This guide explains how the machine works, which specifications to confirm, and how to compare a bag making machine manufacturer before you send an inquiry. It is written for importers, distributors, converters and brand owners who source from China.

What Is an Automatic Corn Starch Bag Making Machine?

An automatic corn starch bag making machine unwinds a roll of film, seals it, cuts it to length and delivers finished bags. The film is the key difference. Corn starch bags use starch-based biodegradable film, often blended with PBAT to improve strength and flexibility.

The film itself comes from a blown film line, which is a separate process. The bag making machine works at the second stage. It follows the same basic principle as a plastic bag making machine or a PE bag making machine. Biodegradable film has one important difference: it can be more sensitive to heat and tension. The machine needs stable temperature and accurate film control to make clean seals.

Corn Starch Film vs. Standard PE Film

•         Sealing window: starch-based film often has a narrower temperature range than PE film.

•         Film tension: softer film stretches more easily, so feeding must stay smooth.

•         Trial runs: each film formula behaves differently, so test your own film before final production.

Key Features of Our Biodegradable Bag Making Machine

Xinghong focuses on the research, development and manufacturing of intelligent bag-making equipment. Our automatic machines offer these features:

•         Automatic operation: film feeding, sealing and cutting run in one continuous cycle.

•         Accurate bag length: Panasonic PLC pulse control gives high precision, a low failure rate and high reliability.

•         Bus control option: a Xinye motion controller connected by Ethernet bus gives fast computing, simple operation and easy addition of custom functions.

•         Remote function: our engineers can connect to your machine and help solve problems on site.

•         Customizable design: we adapt the machine to your bag type, size and film.

•         In-house CNC parts: all key components are made on our own CNC machine tools.

Technical Specifications: Speed, Bag Size and Film Thickness

Speed, bag size and film thickness change with the machine model and bag style. We do not publish one fixed specification for every buyer. We confirm the exact figures in your quotation after we learn your bag and film details. The table shows what we ask for and why it matters.

Buyer tip: ask every supplier to state the speed for your film, not only for standard PE film. Real output on biodegradable film can differ from catalog speed.

Compatible Materials: Corn Starch Film, PBAT and Compostable Film

Material choice affects seal strength, bag feel and shelf performance. Typical film options include:

•         Corn starch film: starch-based film used for compostable bags.

•         PBAT blends: PBAT is a biodegradable polyester. Film makers often blend it with starch for better flexibility.

•         Other compostable films: formulas vary by film supplier, so a sample test is the safest route.

•         Conventional films: laminated and aluminum-plastic composite films, which are common in our existing bag applications.

Send us your film specification and, if possible, a sample roll. Our engineers will review the sealing and feeding requirements with you. Please also ask your film supplier for compostability certificates, such as EN 13432 or ASTM D6400. These certificates apply to the film and finished bag, not to the machine.

Bag Types You Can Produce: 3 Side Seal, Center Seal and Stand-Up Pouches

Our product range covers three-side seal, four-side seal, center seal, stand-up, zipper and nozzle bags. Three core models serve most buyer requests:

•        X600 3 side seal bag making machine: makes flat pouches with three sealed edges.

•        H600 center seal bag making machine: makes bags with a center seal on the back.

•        D600 standup bag making machine: makes stand-up pouches that sit upright on the shelf.

Zipper and nozzle bags need compatible materials, so please confirm that your biodegradable film suits the bag style you want. If you need a bottom seal bag making machine for another bag design, send us your drawing. We will tell you whether we can support it. If you need a paper bag machine, note that this guide covers film-based bags only.

Applications: Food, Shopping, Garbage and Agricultural Bags

Corn starch bags work best for dry and low-moisture products. Our machines already serve bag applications such as nuts, rice, cat food and feed. For biodegradable packaging, buyers commonly consider these uses:

•         Food packaging: dry food, nuts, rice and snacks.

•         Pet food and animal feed: dry products in flat or stand-up pouches.

•         Retail and shopping bags: often made on handle-bag or roll-bag machines.

•         Garbage bags: usually produced on roll-bag machines.

•         Agricultural bags: used for seeds, fertilizer samples and similar goods.

Shopping, garbage and agricultural bags often use different machine styles. If you plan these bag types, send us the size and design, and we will tell you honestly whether our pouch machines fit. For moist, oily or long shelf-life products, run a packaging test first. Biodegradable film can have different barrier performance than standard film.

PLC and Servo Control for Accurate Bag Length and Stable Sealing

Bag length accuracy and seal quality decide how much film you waste. Biodegradable film often costs more than standard PE film, so less scrap protects your margin. We offer two control routes:

•         PLC control: Panasonic PLC pulse control keeps bag length precise and the failure rate low.

•         Bus control: a Xinye motion controller on an Ethernet bus gives fast response, easy installation and maintenance, and room for added functions.

Ask us which drive and control configuration suits your bag size and speed target. We will recommend the setup in your quotation.

Remote Monitoring and 24/7 Online Technical Support

Many overseas buyers worry about service after delivery. Distance should not mean long downtime. Our support covers these points:

•         The software running status of our machines can be viewed remotely.

•         Our engineers can connect to your equipment and help solve problems on site.

•         Video and phone service is available 24/7.

How to Choose the Right Corn Starch Bag Making Machine

Use this checklist when you compare quotations from any bag making machine manufacturer in China:

1.       Define your bag: type, width, length and film thickness.

2.       Confirm your film: corn starch, PBAT blend or another compostable material. Ask for a test plan.

3.       Set your output target: bags per minute, and hours per day.

4.       Check the control system: PLC or bus control, and the brand of key electrical parts.

5.       Ask about support: remote service, response time, spare parts and training.

6.       Compare real delivery time: production time plus shipping to your port.

7.       Request proof: machine running video, factory photos and references that the supplier can verify.

Corn Starch Bag Making Machine Price and Factors That Affect Cost

Buyers often search for bag making machine price in China before they send an inquiry. We cannot give one price for every machine, because the cost depends on your configuration. The main factors are:

•         Machine model and bag style.
