Packaging Tape Buying Guide: Acrylic vs Hot Melt vs Water-Activated Paper Tape

Packaging tape is the cheapest item on a packing bench and the one most likely to cause an expensive problem. A carton that pops open in a courier depot costs you the product, the reshipment, the customer and the time spent dealing with all three. Most of those failures trace back to the wrong tape for the job, not a faulty roll.

There are three main types of packaging tape sold in Australia: acrylic, hot melt and water-activated paper tape. They look similar on the shelf and behave very differently on a box. This guide explains how each one works, where it performs and where it fails, so you can buy the right one for your cartons, your climate and your volume.

The three types at a glance

Acrylic tape uses a water-based acrylic adhesive on a polypropylene (BOPP) film backing. It is the standard general-purpose tape and the one most businesses buy by default.

Hot melt tape uses a synthetic rubber-resin adhesive on the same polypropylene backing. It grabs faster and holds harder, especially on recycled board.

Water-activated paper tape (often called gummed tape or Kraft tape) is a paper backing coated with a starch-based adhesive that is activated with water. It bonds into the carton fibres rather than sitting on top of them.

Acrylic packaging tape

Acrylic adhesive is clear, stable and inexpensive. It is the right choice for most light to medium cartons that are packed, shipped and opened within a few weeks.

Where it performs

• General eCommerce orders, retail dispatch and office use

• Wide temperature range: it stays stable in cold rooms and hot sheds better than hot melt

• Long-term storage, because the adhesive does not yellow or dry out over months

• Clean, clear appearance that does not discolour printed cartons

• Lowest cost per metre of the three

Where it falls short

• Slower initial tack. It needs a firm wipe-down and a few minutes to reach full bond, which matters on a fast packing line

• Weaker hold on recycled or dusty board. If your cartons are high recycled content, acrylic can lift at the edges

• Heavier cartons over about 15 to 20kg need a second strip or a move to hot melt

Best for: standard cartons, long storage, cold-chain and anyone buying on price for everyday dispatch. See our packing tape range for general-purpose and premium-grade options.

Hot melt packaging tape

Hot melt adhesive is tackier and more aggressive than acrylic. It is the tape to reach for when cartons are heavy, the board is rough or the packing line moves fast.

Where it performs

• Instant grab: it bonds on contact, so there is no need to wipe down and wait

• Strong hold on recycled, corrugated and slightly dusty cartons where acrylic struggles

• Heavier cartons, because the adhesive resists the shear forces that make tape peel back under load

• High-speed packing, including tape dispensers and automated case sealers

• Quieter unwind on many grades, which matters in a busy packing room

Where it falls short

• Temperature sensitivity: hot melt can soften above about 50°C in a parked truck or shipping container and become brittle in a freezer

• The adhesive can yellow over long storage, so it is less suited to cartons that will sit on a shelf for a year

• Slightly higher cost per roll than acrylic

Best for: warehouses, 3PLs, manufacturers and anyone moving heavy or recycled-board cartons at volume. Our premium-grade packaging tape is a hot melt formulation designed for exactly this use.

Water-activated paper tape

Paper tape works differently from the other two. When the starch adhesive is wetted, it penetrates the top layer of the carton and sets as it dries. The tape becomes part of the box rather than a layer on top of it.

Where it performs

• Tamper evidence: the tape cannot be peeled off and reapplied without visible damage, which is why it is used for high-value and regulated shipments

• Very strong hold once cured, including on recycled and coated board

• Fully recyclable with the carton. No separation needed, which simplifies waste streams and supports sustainability reporting

• One pass seals the carton. Reinforced versions with fibreglass strands replace multiple strips of plastic tape

• Prints well for branded dispatch without the cost of a printed carton

Where it falls short

• Needs a dispenser that wets the tape. Manual gummed tape dispensers are inexpensive, but it is still a change to the packing process

• Cannot be applied by hand from a roll like plastic tape

• Slower on a line until staff are used to it

• Higher cost per metre, partly offset by needing fewer strips

Best for: eCommerce brands that care about unboxing and sustainability, businesses shipping high-value goods, and anyone trying to remove plastic from their packaging. It also pairs well with plain kraft boxes for a consistent, fully recyclable pack.

Choosing by situation

You ship standard-weight cartons and want the lowest cost. Acrylic. Buy a good 48mm roll, use a pistol grip dispenser and wipe each strip down firmly.

Your cartons are heavy, or made from recycled board, or both. Hot melt. The instant tack and stronger hold are worth the extra few cents per roll, and you will use fewer strips.

Your goods sit in storage for months before dispatch. Acrylic. It ages better than hot melt and will not yellow or dry out.

Your goods go through hot trucks or shipping containers. Acrylic for heat stability, or paper tape if you also want tamper evidence.

Your goods go through cold storage or freezers. Acrylic, or a tape rated specifically for low temperature.

You want a plastic-free, fully recyclable carton. Water-activated paper tape, ideally reinforced if cartons are heavy.

You run an automated case sealer. Hot melt is the usual choice for machine tape, but check the tape width and core size the machine takes.

Other things that affect performance

The adhesive type matters most, but three other choices make a real difference.

Tape width. 48mm is the standard for most cartons. Go to 72mm for large or heavy boxes, or to seal cartons with a single strip over the flap join.

Thickness and backing. Tape is usually specified in microns, counting backing plus adhesive. General-purpose tape sits around 40 to 45 microns, premium grades around 50 or higher. Thicker tape resists tearing on sharp carton edges and holds heavier loads.

Application. Most tape failures come from poor application rather than poor tape. Press the strip down firmly along its full length, run it at least 50 to 75mm down each side of the carton, and keep rolls at room temperature before use. Cold tape does not bond properly.

Core and dispenser fit. Hand tape uses a 75mm core. Machine tape may differ. Our tape dispensers range covers hand-held, bench-mounted and gummed-tape options.

Specialist tapes for specific jobs

If packaging tape is not holding, sometimes the answer is a different product rather than a stronger grade of the same one.

• Filament tape has fibreglass strands and is used for bundling, strapping light loads and reinforcing carton edges.

• Cloth tape tears by hand, resists moisture and is common in building, events and repairs.

• Masking tape is for temporary holds and painting, not for sealing cartons.

• Warning and printed tapes carry "Fragile", "This Way Up" and similar messages on the tape itself, saving a separate label.

• Double-sided tape is for presentation packaging, point-of-sale displays and mounting.

Buying in bulk

Packaging tape is sold by the roll and by the carton, usually 36 rolls of 48mm tape per carton. Cost per metre drops noticeably at carton quantities, and more again for pallet orders. If you are comparing suppliers, make sure you are comparing the same width, length and micron thickness; a cheaper roll is often a shorter or thinner one.

FAQ

Is clear or brown tape better? Neither is stronger. Brown (tan) tape hides the flap join on kraft cartons; clear tape shows printed packaging underneath. Choose on appearance.

Why does my tape keep lifting at the edges? Usually one of three things: recycled or dusty board, tape applied cold, or tape not pressed down firmly. Switching from acrylic to hot melt fixes the first; warming the rolls and wiping down fixes the other two.

Can I use packaging tape on pallets? No. Use pallet wrap or strapping for load containment. Tape is for sealing cartons.

Is paper tape strong enough for heavy boxes? Reinforced water-activated tape, with fibreglass strands, holds heavy cartons well. Standard non-reinforced paper tape is best for light to medium boxes.

Can I get tape printed with my logo? Yes, custom printed tape is available on both plastic and paper backings. Contact us with your artwork and quantity for a quote.
