Packaging tape: how to find the most sustainable for your brand

Materials

Choosing a packaging tape may seem like a fairly straightforward task. Until you realise how many types there are, each with different strengths (literally). Combine that with sustainability concerns and a heap of customisation options and you’ll soon see it’s not as simple as you thought.

But making a choice doesn’t have to be too challenging. To help, we’ve compared two of the most sustainable custom tapes against a few more traditional tapes. Once you know their key features, you can see which ones align with your business and sustainability goals and choose the right one for you.

1. Gummed Tape

Gummed tape is the ultimate paper packaging companion. And yes, we’re a little biased — but with good reason.

Gummed tape is a kraft paper tape with a starch-based adhesive that’s activated by water. When applied to paper packaging, like a cardboard box, it doesn’t just stick like regular tape — it fuses to your packaging. This creates a strong bond and a tamper-evident seal as you can’t remove the tape without ripping the package.

Under the right conditions, it can secure packages up to 15kg in weight. And the packaging — gummed tape included — can be recycled at the kerbside once used. That’s a major advantage over plastic tape, which nearly always can’t be recycled. In fact, we’ve done the maths and found that using gummed tape instead of plastic tape can reduce your carbon footprint by up to 50%.

And the pros don’t stop there. Gummed tape offers a fantastic branding opportunity. You can easily print your logo, slogan and other artwork directly onto the tape, helping your packaging stand out and generating brand awareness.

In short, if you’re using paper-based packaging like mailer boxes or shipping boxes, gummed tape provides strength, style and improved sustainability over plastic tape.

Pros

Durable
Plastic free
Customisable
Kerbside recyclable
Available as FSC certified
Long shelf life

Cons

Needs a tape dispenser
Slow to apply due to bonding process
Only suitable for paper and card packaging

‍

2. Self-adhesive paper tape

Self-adhesive tape is another paper-based tape with similar benefits to gummed tape.

For starters, it’s strong, securing packages up to 10kg. It’s also customisable, so you can add your logo, instructions for handlers or delightful messages for customers. And as the name suggests, “self-adhesive” means it doesn't need any specialised dispensers, making it quick and easy to use.

One key difference between this and gummed tape is that self-adhesive tape uses a solvent to stick to your packaging. The disadvantage here is that it makes it slightly less sustainable than gummed tape’s water-activated bonding adhesive. But an advantage is that it can stick to a wider range of surfaces.

Using self-adhesive tape can still reduce your carbon footprint by up to 20% compared to plastic tape. But it’s important to note that the adhesive means the tape fibres themselves aren’t easily recyclable. Though as long as there’s not a huge amount of tape used, it won’t create any recycling problems for the paper packaging it’s attached to.

Pros

Durable
Customisable
Kerbside recyclable
No dispenser needed
Available as FSC certified
Suitable for a range of packaging materials

Cons

Affected by humidity
Not as durable as plastic tapes
Shorter shelf life than gummed tape (~6 months)

Other tapes

3. Brown polypropylene tape

This is your standard, widely recognised brown parcel tape. It’s cheap and does a good enough job sealing packages. It blends with brown boxes, which might be your desired look, but it can look untidy against different coloured boxes.

Of course, it’s made from plastic, so it’s non-recyclable and has a higher carbon footprint than paper-based tapes.

Pros

Durable
Moisture resistant

Cons

Plastic
Unbranded
Not recyclable
High carbon footprint

‍

4. Clear polypropylene tape

This tape is like brown packaging tape, except it’s transparent. This can be good if you don’t want your tape to conceal your packaging’s designs or instructions.

It’s available in a wide range of widths and thicknesses, which is helpful when you want to reduce the materials you're using. But, once again, it’s a non-recyclable, plastic tape with a higher carbon footprint than paper tapes.

Pros

Durable
Transparent
Suitable for a range of packaging materials

Cons

Plastic
Unbranded
Not recyclable
High carbon footprint
Hard to remove cleanly
Noticeable on darker packaging

‍

5. Coloured polypropylene tape

The difference between this and the other propylene tapes is that it comes in a range of colours. This can be useful when organising packaging during handling and shipping or for drawing attention to it.

Pros

Durable
Transparent
Allows for colour coding
Suitable for a range of packaging materials

Cons

Plastic
Not recyclable
High carbon footprint
Limited colour options

‍

6. Vinyl packaging tape

Vinyl tape is a heavy-duty tape that’s stronger than standard polypropylene (PP) tape. It’s less likely to tear or burst than PP tape and the adhesive can withstand colder temperatures, so it’s potentially a good choice for refrigerated goods.

Pros

Highly durable
Moisture resistant
Variety of colours available
Can be printed on to include instructions

Cons

Plastic
Not recyclable
High carbon footprint

‍

7. Reinforced glass filament tape

Reinforced glass filament tape is a strong, plastic tape suited to particularly heavy goods. The glass filaments can be added to run in one direction or be cross woven. Both of these create extra resistance and added security.

Pros

Strong
Moisture resistant
Suitable for a range of packaging materials

Cons

Plastic
Not recyclable
Leaves residue
Often hard to cut or tear

How to find the best packaging tape for your business

So now you know the key features of the most popular tapes. And you might already have an idea about what you want and what you don’t want in the one you choose. But before deciding, make sure you’ve thought about the following four key considerations.

Ease of use
Branding
Environmental impact
Strength and durability

1. Ease of use

In any business, you want things to run as smoothly as possible. So, when choosing between packaging tapes, think about ease of application and convenience.

Some tapes, like gummed tape, may need a dispenser to activate the adhesive, whilst self-adhesive paper tape can be easily applied without any extra tools. There’s also the issue of noise. Packaging centres can be noisy places, and some tapes, like polypropylene, can add to that quite a bit. Although you can find “low-noise” variations, this can affect your team and slow down the packaging process.

It’s also worth weighing convenience up with sustainability. For example, gummed tape might take that a little bit longer to apply, but with a significantly smaller carbon footprint than plastic tapes, you might decide those few extra seconds are worth it.

2. Branding

Many businesses use a run-of-the-mill tape that simply does what it’s made for. But why not choose one that helps you stand out by going above and beyond its original function?

Using your packaging tape as a marketing opportunity is a great way to drive brand awareness. Custom tapes can get your logo out there and showcase your brand personality. And they’re also an opportunity to delight customers, showing them you pay attention to the little details that add to their unboxing experience.

Because they’re made from paper, gummed tape and self-adhesive tape are perfect for printing on. So consider these as a way to take your packaging from functional to fabulous.

3. Environmental impact

Sustainability may be one of your top priorities. Or it could be something you haven’t really thought about until now. But with the world of commerce shifting towards increased producer responsibilities, it’s best to stay ahead of the curve and reduce your packaging’s environmental impact. Tape included.

Switching from traditional plastic tape to paper-based tape, like gummed or self-adhesive, can significantly reduce your carbon footprint. This matters because customers are increasingly looking to buy from brands with strong sustainability agendas.

So choosing a tape that helps to reduce your environmental impact — instead of increasing it — is not just better for the environment but also for your business.

4. Strength and durability

It goes without saying that if your product doesn’t arrive intact, your customer won’t be happy. This can lead to financial losses in returns, as well as reduced customer loyalty as they switch to more reliable brands.

So, make sure your tape holds up against the weight of your package, weather conditions and any rough handling it might go through during transit.

And don’t forget that heavy-handed treatment isn’t the only risk to your package. Package theft is on the rise. And who’s to say that an opportunist won’t open your package, take what’s inside and seal it back up for your unsuspecting customer to receive?

That’s where stronger tapes come in. These will rip the packaging when removed, making any tampering obvious. Tapes such as gummed tape, with its unique bonding properties, are great deterrents for anyone thinking of practising their sleight-of-hand.
