Carrier / Backing	PE or PP based construction depending on bag film
Adhesive	Acrylic or synthetic rubber adhesive depending on application
Release Liner	PE/HDPE film, anti-static film or printed liner
Adhesive Position	Left / Right / Center
Liner Color	Transparent, white, red, blue or customized according to production requirements

Size Options

Bag sealing tape is commonly used in automatic plastic bag production and is therefore typically produced in narrow widths.

Commonly available tape widths: 9 mm, 10 mm, 12 mm, 14 mm, 15mm, 18 mm and custom widths.

Roll lengths: Standard roll lengths and long length spool rolls are available.

For continuous automatic bag-making production lines, long length spool rolls are recommended. They can improve production efficiency by reducing roll-change frequency.

To help us confirm the correct width, adhesive width, liner width, roll length and core diameter, please send your bag specification or a sample of your existing tape.

---

Adhesive Position: Left, Right or Center

The adhesive position is an important specification when purchasing bag sealing tape. Three common configurations are available:

Left Glue

The adhesive is positioned toward the left side of the release liner.

Right Glue

The adhesive is positioned toward the right side of the release liner.

Center Glue

The adhesive is positioned in the center of the release liner.

The correct configuration depends on your bag-making machine, film feeding direction and bag flap design.

If you are unsure which configuration you need, send us a photo of your current sealing tape, a bag sample or a photo of your production line. We can help identify a suitable configuration.

Compatible Materials

PE / LDPE Bags

Suitable for garment bags, general-purpose packaging bags, textile packaging and many other flexible packaging applications.

The adhesive grade should be selected according to PE surface properties and bag film thickness.

HDPE Bags

Suitable tape grades can be used for HDPE packaging.

Because HDPE surfaces can have relatively low surface energy, sample testing is recommended before mass production.

PP / OPP Bags

Resealable bag sealing tape solutions are also available for PP and OPP bags.

Carrier and adhesive formulations may differ from those used for PE bags, so please specify the exact bag material when requesting a quotation.

BOPP Bags

Suitable for many retail and consumer packaging applications, including garment bags, stationery bags, toy bags, accessory bags and jewelry bags.

Sample testing is recommended when the bag film has coatings, printing or other surface treatments.

Permanent Bag Sealing Tape vs. Resealable Bag Sealing Tape

When selecting bag tape, buyers should first determine whether the bag needs to be opened repeatedly or requires a permanent seal.

Characteristics	Resealable Bag Tape	Permanent Bag Tape
Opening	Repeatedly opened and closed	Primarily used for one-time closure
Typical Uses	Garment bags, stationery bags and retail bags	Courier bags, security bags and mailing bags
Customer Convenience	Higher	Lower
Tamper Resistance	Lower	Higher
Adhesive	Controlled peel for reclosure	Permanent adhesive for strong bonding
Bag Reusability	Typically reusable	Typically not designed to be reused

For garment bags and retail poly bags, resealable bag sealing tape is usually the preferred solution.

For courier bags, poly mailers and security packaging, ask us about permanent bag sealing tape options.

Finger-Lift Release Liner

Bag sealing tape with an extended finger-lift release liner makes the liner easier to remove after the tape has been applied to the bag.

This design is especially useful when:

the end user needs to remove the liner quickly;

gloves are used during packing;

bags are packed on a high-speed production line;

improved opening convenience is required.

Finger-lift dimensions can be customized to suit your bag design.

---

Anti-Static Bag Sealing Tape

Bag sealing tape can be supplied with an anti-static release liner for applications where static electricity may cause production or packaging problems.

Typical applications include:

electronic component packaging;

clean packaging environments;

high-speed film converting;

lightweight plastic film production.

Please specify your anti-static requirement when requesting samples.

---

Printed Release Liner

Bag sealing tape can be customized with printing on the release liner.

Typical printing options include:

company logo;

brand name;

opening instructions;

direction arrows;

warning text;

identification lines;

customized colors.

Printing on the release liner can improve brand recognition and make the liner easier for the end user to identify and remove.

Send us your artwork, printing color and required tape size for evaluation.

Sample Testing Before Bulk Production

Surface treatment, additives, printing, coatings and thickness can vary significantly between plastic film suppliers. For this reason, we recommend testing sealing tape on your actual bag material before placing a bulk order.

Sample evaluation can include:

initial adhesion;

liner release performance;

opening performance;

resealing performance;

adhesive residue;

film compatibility;

machine application;

hot-knife cutting performance;

aging performance under your actual storage conditions.

Free bag sealing tape samples are available for evaluation.

Packaging

Bulk packaging can be customized according to tape size, roll length and customer requirements. Export shipments are packed to help protect the tape from contamination, deformation and damage during transportation.

Customized carton marks, labels and private-label packaging can be discussed for bulk orders.

---

Storage Recommendations

To maintain tape performance and shelf life:

Store sealing tape in a clean, dry indoor environment.

Keep the product away from direct sunlight.

Avoid excessive heat, humidity, dust and contamination.

Keep the original packaging closed until use.

Allow the tape to reach normal production-room temperature before use if it has been stored in a very cold or hot environment.

Actual shelf life varies by adhesive system, liner and storage conditions. Please request the technical data for the selected tape grade when shelf-life documentation is required.

---

Quality Control

Bag sealing tape performance depends on consistent adhesive coating, liner release, winding and dimensional accuracy.

Important quality-control points for bulk orders include:

width tolerance;

adhesive position;

coating consistency;

liner release;

roll winding;

splice control;

roll length / length accuracy;

core condition;

packaging;

batch-to-batch consistency.

If you have specific inspection or quality-control standards, please provide them before production starts.
