Low Noise BOPP Packing Tape
OPALUS PACK manufactures Low Noise BOPP Packing Tape for carton sealing work that needs quieter unwinding and reliable box closure. The tape uses BOPP film backing, a water-based acrylic adhesive layer, and controlled low-noise release treatment. In sample roll checks, total thickness is typically controlled within 40um-55um, with clean slitting edges, smooth roll separation, and stable 3-inch core rotation for hand dispensers and carton sealing machines.
- Material: BOPP film backing with water-based acrylic adhesive

- Widths: 48mm, 60mm, 72mm, or custom slit width
- Lengths: 50m, 66m, 100m, 1000m machine rolls
- Core size: 76mm / 3-inch paper core
- Main use: quieter carton sealing for hand and machine use
Key Features and Benefits
Product Overview
Low Noise BOPP Packing Tape is made for packing areas where ordinary sealing tape creates a sharp pulling sound during repeated carton closure. It keeps the strength and roll handling of BOPP film, while the release side is treated for smoother unwinding. The roll separates with less sudden drag when pulled by hand or fed through a machine head.
Thickness selection depends on carton weight, packing speed, and sealing method. For regular shipping cartons, 40um to 48um total thickness is a practical starting point. For 1000m machine rolls, export cartons, or recycled corrugated cartons with stronger flap rebound, 50um or higher structures are often confirmed by sample testing. The acrylic adhesive layer is usually adjusted around 17um-25um to balance initial tack, peel adhesion, holding power, and unwind control.
OPALUS PACK checks slitting edge cleanliness, +/-1mm width tolerance, roll face flatness, and 76mm core fit. Batch comparison can include unwind feel, peel adhesion reference, carton flap holding, edge lifting, and roll appearance from different lots.
Benefits
- Quieter unwind than standard BOPP sealing tape during repeated carton closure.
- Controlled release treatment helps reduce sudden drag and uneven tape feeding.
- Water-based acrylic adhesive supports bonding on common corrugated cartons.
- 4.5-6.5 N/25mm peel adhesion reference helps confirm sealing strength.
- Clean slitting edge and +/-1mm tolerance improve dispenser handling.
- Batch checks help keep unwind, adhesion, roll profile, and appearance consistent.
How does low-noise unwind control improve daily carton sealing work?
Low noise BOPP packing tape is not just a standard roll with a quieter label. The lower unwind sound comes mainly from the release side of the BOPP film, where controlled back coating helps the roll separate more smoothly. At a busy packing bench, this reduces the sharp tearing sound operators hear many times per shift. On automatic carton sealing machines, stable unwind tension also helps the tape feed through the head without roll jumping or sudden drag.

Applications
- Manual carton sealing at packing benches and warehouse workstations
- Hand dispenser use where repeated tape noise affects operators
- Semi-automatic carton sealing machines for medium-volume packing
- Automatic case sealing lines using 1000m machine rolls
- E-commerce cartons, shipping cartons, and standard box closure
- Recycled corrugated cartons after sample bonding confirmation
What should be checked before using this tape on recycled corrugated cartons?
Recycled corrugated cartons may have rougher liners, more dust, lower surface strength, or uneven surface coating. Before confirming the tape specification, test the actual carton material with the planned roll width, tape length, application pressure, and storage condition. The acrylic adhesive should show stable initial tack, clean wet-out, and controlled flap holding. For heavier cartons or humid storage, sample checks can include peel adhesion, >= 24 h holding power reference, carton flap rebound, edge lifting, and batch unwind consistency.
FAQ
Is Low Noise BOPP Packing Tape completely silent?
No. It is designed for lower and smoother unwind noise than standard BOPP carton sealing tape. Sound varies by roll speed, dispenser type, tape width, and machine setting.
Can this tape be used on automatic carton sealing machines?
Yes. It can be supplied as 1000m machine rolls with a 3-inch core. Confirm roll diameter, unwind tension, roll face flatness, and machine head fit.
Which thickness is suitable for regular carton sealing?
For many standard cartons, 40um to 48um total thickness is commonly selected. Heavier cartons may require 50um or higher structures after sample testing.
Can OPALUS PACK produce custom width and length?
Yes. OPALUS PACK can produce 48mm, 60mm, and 72mm widths, plus custom slit widths and roll lengths for hand or machine use.
