Do you know seal tape?
- Oct 30, 2018 -

Also known as bopp tape, packaging tape(, etc., it is based on BOPP biaxially oriented polypropylene film as a substrate, and evenly coated with pressure-sensitive adhesive emulsion to form a layer of glue ranging from 8μm to -28μm. It is an indispensable item in light industrial enterprises, companies and personal life. The country does not have a perfect standard for the tape industry. There is only one industry standard. QB/T 2422-1998 sealing BOPP pressure sensitive adhesive tape to BOPP original film After high-pressure corona treatment, one surface is rough, and the glue is applied to the top to form a parent roll, which is then cut into small rolls of different specifications by a slitting machine, which is the tape we use every day. Pressure-sensitive adhesive emulsion, the main component is butyl ester.

 Sealing tape can be further divided into: special kraft paper tape for sealing, printing tape, special sealing tape for food, special tape for cold storage, color tape


Tape specifications

BOPP sealing tape specifications are expressed by "width × length × thickness", where "width" is the width of the tape, generally expressed in mm or cm, generally ≥ 10mm, as early as the 1980s, common specifications are: 72mm, 60mm, 50mm, 30mm, etc.; nowadays, has gradually changed to: 60mm, 48mm, 45mm, 40mm, 30mm, etc.; "long" is the total length after the tape is opened, generally expressed by "m" or "code" (1 yard = 0.9144m), common lengths are 50m, 100m, 150m, 200m, 500m, etc.; thickness refers to the total thickness of BOPP original film + adhesive layer (unit: micron, μm), commonly used 45 ~ 55μm. Such as "50mm × 100m × 50μm"

The calculation method of the unit price of each roll of tape: the tape industry usually uses “yuan/square meter” to calculate the price of the tape, then “price per roll = width (m) * length (m) * square price”

Sealing tape features

High-quality and high-performance tapes perform well even in extreme weather conditions, and are suitable for storage in warehouses, shipment of containers, and prevention of goods theft, illegal opening, etc. Available in up to 6 colors and different sizes. Neutral and personalized sealing tape

Unitization: This is one of the biggest features of wrap film packaging. With the superior winding force and retracting property of the film, the product is compactly and fixedly bundled into one unit, so that the scattered small pieces become a whole, and the product does not have any looseness and separation even under the unfavorable environment, and there is no sharpness. Edge and stickiness to avoid damage. Primary protection: Primary protection provides surface protection of the product, forming a very light, protective appearance around the product to achieve dust, oil, moisture, water and security. It is especially important that the wrapping film package makes the packaged articles evenly stressed, and avoids damage caused by uneven force. This is not the case with traditional packaging methods (bundling, packaging, tape, etc.). Compressive fixation: The product is wrapped by the retractive force of the stretched film to form a compact, space-saving unit, so that the trays of the product are tightly wrapped together, which can effectively prevent the products during transportation. The mutual misalignment and movement, while the adjustable tensile force can make the hard product close to each other, making the soft product tight, especially in the tobacco industry and the textile industry. Cost-saving: The product packaging can be effectively reduced by using the wrapping film. The winding film is only about 15% of the original box packaging, about 35% of the heat shrinkable film, and about 50% of the carton packaging. At the same time, it can reduce the labor intensity of workers, improve packaging efficiency and packaging grade.

The main advantage

? Thin thickness, good performance and price ratio? Transparent appearance, double-sided adhesive? Non-toxic, odorless, safe? Easy to use, high efficiency? High anti-buffering strength? Good retraction rate? Anti-piercing? it is good 

Sealing tape characteristics

Instant Adhesive Force - The sealing tape is sticky.

Fixing ability - even with a small amount of pressure, it can be glued to the workpiece according to your ideas.

Easy to tear - easy to tear off the tape without the tape stretching and dragging.

Controlled deployment - the sealing tape can be pulled away from the tape in a controlled manner, neither too loose nor too tight.

Flexibility - The sealing tape can be easily adapted to sharp curves.

Thin – the sealing tape strip does not leave thick edge deposits.

Smoothness - The sealing tape feels smooth and does not irritate the hands when pressed.

Anti-transfer - no adhesive will be left after the sealing tape is removed.

Anti-solvent - The backing material of the sealing tape prevents solvent penetration.

Resistance to chipping - the sealing tape does not have cracks.

Anti-retraction - the sealing tape can stretch along the curved surface without retraction.

    Anti-stripping - the paint will be tightly fastened to the backing of the sealing tape.
