Environmental OPP Bag Sealing Tape

Resealable OPP/BOPP Bag Sealing Tape for PE Plastic Packaging Bags

Environmental OPP Bag Sealing Tape is designed for plastic bag production and flexible packaging. This double-sided pressure-sensitive sealing tape provides a clean, convenient closure for bags that need to be opened and resealed.

Zhuolv supplies OPP/BOPP bag sealing tape in multiple widths, adhesive widths, roll lengths and glue positions to match different bag-making machines and packaging requirements. Common applications include garment bags, stationery bags, gift bags, socks bags, hosiery bags, magazine bags, toy bags and other transparent PE or poly packaging.

With bag sealing tape manufacturing experience since 2000, Zhuolv supplies standard products and supports OEM and customized orders.

Current Zhuolv listings include 13 × 4 × 6 mm and 12 × 5 × 7 mm BOPP sealing tape configurations. Another product listing specifies 12 mm film width with 4 mm water-glue width and 6 mm oil-glue width, with center, left or right glue positioning.

Important: Select the tape specification according to the bag material, bag thickness, bag-making machine, required resealing performance and application temperature. We recommend testing samples on the actual packaging film before confirming a bulk order.

Measurements Explained: What Does 13 × 4 × 6 mm Mean?

When selecting bag sealing tape, the overall tape width is only one part of the specification. A 13 × 4 × 6 mm configuration normally means:

13 mm: overall film/liner width

4 mm: adhesive width on one side

6 mm: adhesive width on the other side

Likewise, 12 × 5 × 7 mm represents a different combination of liner width and adhesive coating widths. The correct configuration depends on the bag flap design and the position where the tape is installed.

If you are not sure which specification is suitable, send us:

Your current tape specification

Bag material

Bag thickness

Bag size

Bag-making machine brand/model

Photos of your current tape and bag

Our team can recommend a matching specification based on these details.

Resealable vs. Permanent Bag Sealing Tape

Zhuolv supplies both resealable and permanent sealing solutions. Choose the version according to whether the finished bag is intended to be reopened.

For clothing, stationery and retail display bags that customers may open more than once, the resealable version is normally the better choice. For courier bags, security mailers and other applications where reopening should be prevented, ask us for permanent bag sealing tape instead.

Glue Position: Left, Right or Center?

Zhuolv offers left, right and center glue-position options to match different bag-making machine configurations.

Left Glue

Suitable when the bag-making machine requires the adhesive lane to be positioned toward the left side of the liner.

Right Glue

Suitable for production lines using the opposite installation direction.

Center Glue

Used when the adhesive position needs to remain centered.

When requesting a quotation, tell us your required glue direction. If you are replacing another supplier's tape, sending a photo or physical sample is the easiest way to reduce specification mistakes.

REACH-related documentation

RoHS-related documentation

Material declaration

Adhesive information

MSDS/SDS

Third-party testing

Frequently Asked Questions

1. What is Environmental OPP Bag Sealing Tape used for?

It is mainly used for producing self-sealing and resealable plastic bags, including garment bags, stationery bags, gift bags, socks bags, magazine bags, toy bags and other retail packaging.

2. Is Environmental OPP Bag Sealing Tape reusable?

Yes. The resealable version is designed for repeated opening and closing of suitable plastic bags.

3. Can Environmental OPP Bag Sealing Tape be used on PE bags?

Yes. OPP/BOPP sealing-tape versions are commonly used with PE bags. Because PE film formulations vary, sample testing is recommended before bulk production.

4. Can this tape be used on OPP/BOPP bags?

For OPP/BOPP bags, a PE/HDPE liner sealing tape is often a better option. Tell us your bag material so we can recommend the appropriate construction.

5. What does 13 × 4 × 6 mm mean for bag sealing tape?

It describes the overall liner width and the widths of the two adhesive lanes. This is an important specification when matching the tape to the bag flap and bag-making machine.

Long-length rolls and spool formats are available for continuous production. Machine compatibility should be confirmed according to roll dimensions, glue direction and machine model.

14. Is Environmental OPP Bag Sealing Tape biodegradable?

Do not assume that standard OPP/BOPP sealing tape is biodegradable. If biodegradability, recycled content or another environmental claim is required, request a specifically qualified material and supporting documentation before ordering.

15. What information should I send for a quotation?

Please send the bag material and thickness, tape size, roll length, glue direction, quantity, machine model, destination country and any customization or compliance requirements.
