5 Packaging Mistakes Small UK Businesses Make (And How to Fix Them)

Packaging is one of those areas where small businesses tend to muddle through rather than make deliberate decisions. You find something that works well enough, stick with it, and move on to the next problem. The trouble is that "well enough" packaging often costs more than it should, lets products down in transit, and misses straightforward opportunities to make a better impression on customers. Here are five mistakes that come up repeatedly, and what to do about each one.

1. Using the wrong tape for the job

Not all tape is suited to all applications, and using a general-purpose or low-grade tape on parcels that go through a courier network is a genuine risk. Packages get thrown, stacked, and exposed to temperature changes and moisture during transit. Tape that performs fine in a warm stockroom can lift, split, or lose adhesion entirely by the time a parcel reaches the other end of the country.

The fix is straightforward: match the tape to the job. Heavy cartons need a stronger adhesive and a more robust film than light mailer boxes. Shipments going into cold storage or travelling in winter need tape rated for low temperatures, typically those using an acrylic adhesive rather than natural rubber. Polypropylene tape works well as a general option, while PVC offers stronger adhesion and better performance under pressure. Rajapack's packaging tape guide gives a useful breakdown of how to match tape type to carton weight and shipping conditions, which is a sensible starting point if you are not sure what you currently need.

2. Ignoring the branding opportunity on the outside of the box

Plain brown tape on a plain brown box is a missed opportunity at one of the few moments you have guaranteed, uninterrupted attention from your customer. The parcel sitting on their doorstep or desk is the first physical thing they receive from you, and it shapes their impression before they even open it.

Custom printed tape is one of the most cost-effective ways to fix this. It works across any box, bag, or carton you already use, so it does not require a redesign of your entire packaging setup. It also adds a layer of tamper-evidence, since a broken print pattern is immediately visible in a way plain tape is not. Businesses looking for a reliable source with full in-house production often work with Prima Tapes & Labels, based in Orpington, Kent, who have been manufacturing bespoke printed tapes and custom labels for over 60 years, with the entire process from artwork through to delivery managed on site.

3. Using generic labels that are not fit for purpose

Labels do a lot of work. Shipping labels need to stay readable and scannable through handling and weather. Product labels need to stay bonded to their surface through refrigeration, humidity, or repeated handling. Hazard labels need to meet compliance standards. Food labels carry their own regulatory requirements around allergens, nutritional information, and ingredient declarations.

The mistake many small businesses make is treating labels as an afterthought and buying whatever is cheapest or most convenient at the time. A label printed on the wrong material, with the wrong adhesive, or without the correct compliance information can cause real problems, from parcels rejected by couriers to products falling foul of food safety rules. Businesses producing food products in particular often benefit from working with a specialist, such as Food Labels, who combine compliance checking with printing under one roof, so labels are legally correct before they go anywhere near a product.

4. Choosing box sizes that do not match the product

Oversized boxes create two problems at once. They increase shipping costs because most UK couriers now price on dimensional weight rather than actual weight, meaning a light product in a large box costs more to send than the same product in a correctly sized one. They also require more void fill to stop contents moving, which adds material cost and packing time.

Undersized boxes are just as problematic in a different way. A box that is too small puts pressure on the seams and the tape, making failure in transit far more likely. Getting box sizing right is one of the easiest ways to cut both damage rates and shipping spend simultaneously. If dimensional weight is a new concept, Interparcel's guide to calculating dimensional weight is a clear, practical explanation of how the calculation works and what steps to take to reduce the impact on shipping costs.

5. Treating packaging as a cost rather than a touchpoint

The instinct to cut packaging costs is understandable, especially for businesses operating on tight margins. But the calculation changes when you factor in what poor packaging actually costs: damaged goods, replacement shipments, customer service time, and the harder-to-measure impact of a bad first impression.

As one supply chain writer put it in Northern Life, for an e-commerce business the package is the only physical touchpoint you have with the customer. Businesses that treat it as such, and invest modestly in quality tape, appropriate box sizes, and considered labelling, tend to see fewer complaints, fewer returns, and more repeat orders. The cost of doing it properly is nearly always lower than the cost of doing it badly.
