The difference between reinforced and standard gummed paper tape comes down to fibreglass. Reinforced water-activated tape has fine fibreglass filaments running through the paper, giving it far greater tensile strength for heavy or well-travelled parcels, while standard gummed tape is plain paper and adhesive that seals lighter cartons perfectly well at a lower cost. Choose reinforced for anything heavy, bulky or bound for a long journey, and standard for everyday, lighter shipments.
Both are types of water-activated gummed paper tape, and both create the same permanent bond that makes gummed tape so popular for secure, plastic-free packaging. The right choice simply depends on what you are sending. This guide explains how each one is built, where it performs best, and how to pick the correct tape for your parcels.
What gummed paper tape is
Gummed paper tape, also called water-activated tape, is a kraft paper tape coated with a starch-based adhesive that stays dry and inactive until it meets water. Once moistened, the adhesive activates and soaks into the fibres of the cardboard, so the tape and the box effectively become one. This is why a single strip holds so well and why the seal is tamper-evident: you cannot peel it back and re-stick it without leaving obvious damage. We explain the wider benefits in our guide to why gummed paper tape seals boxes better.
Gummed tape comes in two main grades. The core paper and adhesive are the same, but one has an extra layer of reinforcement built in. Understanding that single difference is the key to buying the right tape.
Standard gummed paper tape explained
Standard, or non-reinforced, gummed paper tape is made from paper and starch adhesive with no added filaments. It still forms a strong, permanent bond and gives you all the everyday advantages of gummed tape: a clean paper finish, tamper evidence, and single-strip sealing on most cartons.
Because it has no fibreglass, standard tape has a lower tensile strength, which makes it ideal for lighter and medium-weight boxes rather than the heaviest loads. For a large share of e-commerce, retail and warehouse shipping, standard gummed tape is all you need. It is also the more economical option, so if your parcels are typically light and travelling short to moderate distances, it is usually the sensible default. It pairs well with a tidy sealing technique such as the H-taping method to keep every seam secure.
Reinforced gummed paper tape explained
Reinforced gummed paper tape sandwiches a layer of fibreglass filaments between two plies of kraft paper. Those filaments, which typically run both along and across the tape, dramatically increase its tensile strength so it resists tearing, stretching and splitting under load. The adhesive still penetrates the box fibres to form a permanent bond, but now the tape itself is far harder to break.
This makes reinforced tape the right choice for heavier cartons, bulky items, double-walled boxes and parcels facing long transit routes or rough handling. In many cases a single strip of reinforced tape will securely seal a box that would otherwise need multiple passes of a weaker tape. If your goods are valuable, heavy or heading a long way, the extra strength is well worth it. Reinforced gummed tape is still made from paper and remains widely recyclable, so you keep the plastic-free credentials covered in our guide to recyclable, plastic-free parcels.
Reinforced vs standard: how to choose
The decision usually comes down to weight, distance and value. As a quick guide:
- Parcel weight: lighter and medium boxes seal well with standard tape; heavier cartons benefit from reinforced. Remember that a Royal Mail medium parcel can weigh up to 20kg, so heavier boxes really do need a stronger seal - you can check the current limits on the Royal Mail parcel guidance.
- Journey length: short local deliveries are gentle on a seal, while long-distance or multi-hub routes involve more handling, which favours reinforced tape.
- Contents value: for high-value or fragile goods, the added security and tamper evidence of reinforced tape gives extra peace of mind.
- Box construction: single-wall cartons pair fine with standard tape; double-wall and heavy-duty boxes are better matched with reinforced.
- Budget: standard tape costs less per roll, so if your parcels are light there is no need to pay for reinforcement you will not use.
If your range spans both light and heavy parcels, many businesses simply keep both grades on the bench and reach for the right one per order. Whichever you choose, gummed paper tape gives a cleaner, more secure result than plastic parcel tape, as we set out in our comparison of paper, polypropylene and PVC tape.
Can you print on reinforced and standard tape?
Yes. At Fast Printed Tapes we custom-print water-activated gummed paper tape in 48mm width, in white or brown kraft, and in both standard and reinforced grades. The design is printed directly onto the tape using full-colour, water-based digital inkjet, and the pattern repeats along the length of the roll so your branding runs continuously across every parcel. Printing sits on the surface of the paper and does not weaken the fibre bond, so a printed reinforced tape is just as strong as a plain one.
Branded tape does more than look good. It turns the seal itself into a marketing surface, reinforces trust at the doorstep, and makes tampering even more obvious because any interference disrupts a recognisable printed pattern. You can read more about that effect in our piece on how branded tape boosts e-commerce sales.
Frequently asked questions
Is reinforced gummed tape stronger than standard gummed tape?
Yes. Reinforced tape contains fibreglass filaments that give it a much higher tensile strength, so it resists tearing and holds heavier boxes securely. Standard tape has no filaments and is best suited to lighter and medium-weight cartons.
Do I need reinforced tape for every parcel?
No. For light and medium parcels travelling short to moderate distances, standard gummed tape seals reliably and costs less. Reinforced tape is worth choosing for heavy, bulky or high-value items, and for parcels facing long or rough journeys.
Is reinforced gummed paper tape still recyclable?
Reinforced gummed tape is paper-based and widely recyclable with cardboard in most kerbside and commercial streams. The small amount of fibreglass is generally handled within standard paper recycling, so you keep the plastic-free benefits of gummed tape.
What width of gummed tape do you print?
We print water-activated gummed paper tape in a single 48mm width, available in white or brown kraft and in both standard and reinforced grades. The maximum print height is 40mm within that 48mm tape, leaving clear margins along the edges.
Does printing weaken the tape?
No. The design is applied with water-based inkjet on the surface of the paper and does not affect the starch adhesive or the fibreglass reinforcement, so printed tape performs the same as plain tape of the same grade.
