Carton Sealing Tape is a pressure-sensitive adhesive used to seal and reinforce corrugated boxes. Specifically, it refers to high-performance tape made from BOPP (biais-oriented polypropylene) film coated with water-based acrylic adhesive (commonly called 'water-based adhesive').
Base Material: BOPP film, which provides the tape with tensile strength and toughness.
Adhesive: Water-based acrylic adhesive. This is an environmentally friendly adhesive with water as the dispersion medium, which forms a high strength bonding layer after water evaporation.
(1)Environmental Safety: No irritating odor, no organic solvents (VOCs), friendly to operators and the environment.
(2)Strong Weather Resistance: stable performance, excellent resistance to ultraviolet, high and low temperature, long-term storage is not easy to age, yellow or fall off.
(3)Adhesive Stability: Excellent adhesion (holding force), with a stable bonding effect over time.
(4)Friendly to Cartons: Strong bonding with corrugated board fibers, making it an ideal choice for packaging cartons.
Hydrogel technology is the mainstream of medium and high-end box sealing tape at present. Its product types are mainly divided according to appearance and function:
Transparent Adhesive Tape: the most versatile type. It has high transparency and light transmittance, which can clearly display the information on the carton and look neat.
Color Water-Based Adhesive Tape in Beige or Kraft Paper Color: Made from dyed BOPP substrate, its appearance closely resembles traditional kraft paper, commonly used in industrial or brand packaging where aesthetic appeal is prioritized.
Colorful and Printed Water-Based Adhesive Tape: Customizable in various colors or printed with corporate logos, warning messages, etc. The water-based ink printing complements its eco-friendly features.
Standard Water Seal Box Tape: meets the vast majority of daily and industrial packaging needs, balancing cost and performance.
High Tack Adhesive Box Sealing Tape: The initial tack is improved by adjusting the acrylic formula, suitable for rough or dusty paper boxes, as well as heavy goods.
Low Temperature Water Seal Box Tape: the special formula to keep good adhesion in cold environment, solving the problem of ordinary tape can not stick in winter.
Water-resistant reinforced adhesive tape: While BOPP substrate inherently has moisture resistance, this product features optimized adhesive-substrate bonding for enhanced waterproof sealing performance.
The characteristic of water glue is excellent adhesion, but the initial adhesion may be slightly lower than that of hot melt glue. Therefore, special attention should be paid to the selection:
Initial Tack: The adhesive strength of the tape at the moment of application. For automated packaging equipment or situations requiring rapid bonding, select water-based adhesives labeled 'high initial tack'.
Adhesion: The ability of adhesive tape to resist displacement under pressure for a long time. This is the biggest advantage of water adhesive. For cartons that need long-distance transportation and stacking storage, strong adhesion can ensure that the seal does not lift or crack for a long time.
Suggested Choices:
Most standard cartons can be used with standard viscosity water glue.
For heavy objects, rough surface cartons, or winter use, be sure to choose high adhesion or low temperature water glue products.
Thickness directly determines the mechanical strength and impact resistance of the tape.
Measurement Unit: micrometer (μm) or "filament" (1 filament = 10μm).
Suggested Choices:Lightweight packaging/e-commerce small items: 40μm-45μm(4.0-4.5mm silk).
Standard Logistics/Factory Shipping: 48μm-55μm(4.8-5.5 microns. This is the most cost-effective general range.
Heavy Packaging/Large Cargo: 55μm (5.5 microns) or larger.
Note: Low-quality adhesive tape may artificially inflate its thickness by adding calcium carbonate, resulting in a whitish appearance and increased brittleness. High-quality water-based adhesive tape, on the other hand, offers superior transparency and flexibility.
Length: Note that compare the actual length of each roll, not just the diameter.
width ：
45mm / 48mm: The most commonly used width, suitable for small and medium-sized cartons.
60mm / 72mm: Suitable for large cartons or applications requiring wider sealing surfaces.
Enhance Transparency: Premium water-based adhesive tape features high transparency, with the BOPP substrate appearing exceptionally clear.
Gel Surface: A refreshing feel, non-sticky, with an even adhesive layer. The tape's back (release side) remains clean after removal, with no adhesive residue.
Smell: High quality water glue tape has almost no irritating smell.
Try it Out: Place a sample on a cardboard box, press firmly, then quickly tear it open. Listen to the sound—smaller sounds indicate better quality of the base material and adhesive. Then slowly pull to feel its toughness and stickiness.
Consult Suppliers: Clearly inform your usage scenario (e.g., cargo weight, storage environment, whether to use automated equipment) and request recommendations for suitable water-based adhesive models.
Sum Up ：
Choosing water-based acrylic adhesive for Carton Sealing Tape is a smart move for safety, eco-friendliness, durability, and stable performance. While the cost per roll may be slightly higher, its reliable sealing effect and extremely low failure rate can help you avoid greater losses caused by packaging cracks, making it a more cost-effective choice in the long run.
