Label for bag

Labels for bags are designed for marking products supplied in woven polypropylene bags, as well as other types of fabric bags made of jute, linen, or hemp. :contentReference[oaicite:0]{index=0}

Suitable for labeling:

• Food products: cereals, flour, sugar, grain
• Fuel materials: pellets, fuel briquettes
• Agricultural products: fertilizers, compound feed, seeds
• Industrial products: polymer granules, chemical powders

Sewn-in nylon labels can be used to mark the following types of bags:

1. Polypropylene bags (PP)
This is the most common segment for this type of labeling. The label is sewn into the top seam during packaging.
Sugar and flour bags: standard way to indicate specifications, weight, and manufacturer.
Grain and cereal bags: the label remains securely fixed during multiple handling operations.
Bags with liners: the label is stitched simultaneously with the main fabric and polyethylene liner.

2. Fabric bags (natural)
Due to the high weave density, the label is firmly fixed in the seam.
Jute bags: for coffee, cocoa beans, or premium seeds.
Cotton and linen bags: often used for сувенир products or small batches of flour.

3. Paper (kraft) bags
Although paper is not fabric, multi-layer kraft bags are often stitched with thread (sewn neck), allowing a nylon label to be inserted into the seam.
Used for charcoal and dry construction mixes (when sewn closure is applied instead of valve type).

4. Mesh bags (vegetable nets)
For nets supplied as individual bags with ties or for stitching.
Potatoes, onions, carrots: the label (often called “wineglass” or ribbon type) is sewn into the bottom or side seam during manufacturing, or into the top seam during packaging.

The sewn-in nylon label is attached during the stitching of the bag neck using a bag sewing machine. This method is suitable for products with a woven structure or soft edge that allows the needle to pass through without damaging the material.

Bags with products must be equipped with sewn-in labels. Self-adhesive labels do not hold on bags with bulk materials.

Nylon is used for manufacturing sewn-in labels.

This label has a width of 70 mm and a length of 105 mm. Sewn-in labels are produced on demand, so the price depends on size and material.

Minimum order quantity for bag labels 70×105 mm — 250 pcs. Printing is performed in black color. Other color options are available. The print is durable and resistant to abrasion.

Production time: 1–4 working days. Labels are supplied in rolls with cut marks.

Printing is performed using a label printer and textile ribbon.

Why choose nylon for these bags?

• Strength: nylon does not tear at the needle puncture point.
• Durability: printing does not wash out or fade even in unheated warehouses.
• Flexibility: easily passes through bag sewing machines together with thread.

Barcodes can be printed on sewn-in labels to enable automated accounting in production and warehouses.

The barcode is read by a barcode scanner.

Even after crumpling and friction, the barcode remains readable, especially with omnidirectional scanners.

We tested linear barcode scanners for reading wrinkled and worn textile labels.

Not all scanners can read damaged textile labels.

The Datalogic QuickScan Lite QW2100 handled this task perfectly.

The scanner confirms successful reading with a green spot and a sound signal.

These scanners failed to read the barcode:

Godex GS-220U.

Zebex Z-3100.

The use of barcodes and 2D codes on bag labels enables full traceability across the entire production chain — from raw material suppliers and logistics to incoming inspection, production processes, and finished goods control. Serial numbering of bags ensures the highest level of traceability down to each individual package. This approach guarantees quality at every stage.
