Paper yarn bag/sack making machine is a patent machinery with innovation and unique technology based on 20years practiced experiences. We are only one producer and exporter for this patent bag/sack machine in China.

Paper Yarn Bag is the latest type packaging bag made by the latest new process of weft surrounding continuously, without centre joint. Generally, complex packing bags/bags consist of 2-layer of national standard kraft paper inside and outside, between which is a glued film formed by polyester yarn and PVA, thus combined three into one. Without condensations aldehyde treatment, so the used bags can be recycled, without any pollution to environment after going through hydrolysis. In addition, The paper yarn bag/sack made by using our machine have good features of Lower broken rate & High intensity, Proof moisture and air permeability, 

High aging resistance,High-temperature resistance, Stack without slipping,Environmental protection and be recyclable.

The bags produced by using our machine, adapt to the technology of reinforce are high strength, High aging resistance High-temperature resistance, moisture proof and ventilating.To meet the customers’ requirements, our machine can produce standard-bags, widened bags, any length of bags, film and wet proof bags, M-type folded and pin-hole pricking bags. The raw materials are no poison, no harm. All products are widely used to package cement, chemical goods, cereal, dry and fresh goods, starch, casein, forage, building material and minerals such as powder or granule. The waste bags can be recycled through dissolving in high temperature water. They are environmental and really green packing products.

Our machine can help you to realize producing below type industrial bags/sacks: 

Open paper bag

Sealing (valve) paper bag;

Micro glue paper bag;

Paper bag with interlayer or inner polyethylene lining;

Sewing paper bags;Lamination and asphalt bags;

There is a white layer on the top of the paper bag;

Moisture barrier bag an so on.

Our machine is the quite unique one to produce the reinforced paper bag is a unique packaging form. There are many market area is blank in the world now. The bags made by our machine, mainly used for drying construction mixtures, agricultural products and food packaging. 

By using high-quality kraft paper with special strength synthetic line and special alcohol adhesive, could provide good breathable product storage It has special strength, so it is recommended to package products designed for long-distance transportation, 

or this kind of reinforced bag/sack that are often transported by hand from one mode of transportation to another. 

Paper Yarn bag making machine can produce bags as below character:

Any size (from standard to original);

Any structure (open and closed, with any valve position and type);

Any number and layers (brown or white kraft paper, polyethylene laminated paper, asphalt paper, polyethylene film);

With any perforation option (by bag yard, per layer and per layer);

Any complex and colored image.
