Product Detail

High-Capacity Container Flat Flexitank Bag Making Machine

Designed for bulk liquid packaging, the Container Flat Flexitank Bag Making Machine delivers robust performance and high precision in producing large-format flexitank bags. Compatible with all heat sealing materials, including pure PE, it effortlessly handles ultra-wide films up to 4050mm, making it ideal for manufacturing container liners and heavy-duty transport bags.

This system forms bags up to 4000mm wide and 1600mm long (double format), with a solid industrial build that ensures reliable 24/7 operation. Its advanced sealing technology and stable output at 2.5 bags per minute make it the go-to solution for food-grade, chemical, and agricultural liquid packaging.

Engineered for scale and consistency, this flexitank bag-making machine is the solution for efficient, high-volume container liner production.

What is Flat Flexitank?

A flat flexitank is a type of disposable liquid container made of multiple layers of polyethylene (PE) with a strong outer polypropylene (PP) fabric layer. What makes it unique is its flat, rectangular shape that fits more snugly into standard 20-foot containers, reducing wasted space and improving load balance.

Flat flexitanks are typically used to carry non-hazardous liquids such as:

▪ Edible oils (soybean oil, palm oil, etc.)

▪ Liquid sweeteners and syrups

▪ Wine, juice, and beverages

▪ Industrial oils and lubricants

▪ Non-dangerous chemicals and additives

Advantages of Flat Flexitank Design

Better container utilization

Flat design fills out the corners of the container, reducing wasted space.

Improved transport safety

Reduced shifting during transit leads to fewer accidents or leaks.

Efficient loading and unloading

The even shape allows for quicker filling and smoother discharge.

Stack-friendly and compact before use

Easier to store and transport empty units.

How Does it Differ from Traditional Flexitanks?

Feature Flat Flexitank Traditional Flexitank
 Shape  Flat and box-shaped  Cylindrical or pillow-shaped
 Space Efficiency  Maximizes container space, fewer voids  Leaves gaps in container corners
 Stability  More stable during transport  May shift if not packed tightly
 Filling & Discharge  Even liquid distribution, faster flow  May require more handling time
 Load Pressure  Lower pressure on container walls  Higher pressure on points of contact
 Installation  Usually simpler with guided folding  May need more bracing or fitting effort
