Custom Pet Food Mylar Bags That Reseal

Barrier Layers and Pet Food Freshness

Dry pet food contains fats that turn stale when exposed to oxygen and light. A foil or metallised inner layer blocks both, while the outer layer carries the print. For high-fat foods such as raw-coated kibble or meaty treats, a stronger barrier is worth the small extra cost, because a stale smell puts fussy pets off their food and leads to complaints.

Food-contact grade inner films are available on request, and you should mention the product type when asking for a quote. We do not make shelf-life claims, because freshness depends on your recipe, the fill process and storage, but a well-sealed foil bag gives your product the best chance of staying as you made it. The barrier layers are compared in the board and card types guide, which has a section on films.

Zips, Tear Notches and Handles

The zip is what owners interact with most, so choose it carefully. A standard press-to-close zip suits treat pouches. Larger kibble bags benefit from a wider, stronger zip or a slider zip that closes with one pull, which is much easier when the bag is heavy and floppy. A tear notch above the zip lets owners open the bag cleanly without scissors.

Large bags can include a punched handle or a die-cut grip, making them easier to carry from the shop to the car. Hang holes suit treat pouches displayed on pegs. Each of these extras adds a little to the cost, so we will suggest which ones make sense for each bag size.

Test the zip with your actual product before committing to a large run. Fine crumbs from baked biscuits and powdery coatings on freeze-dried treats can settle in the zip track and stop it closing. A slightly deeper header above the zip, or a zip set a little lower from the top seal, gives crumbs somewhere to fall and keeps the closure working for the life of the bag. Single-use sachets without a zip are covered on the heat-seal mylar bags for samples page.

Design That Speaks to Owners

Pet owners buy with their hearts and their heads. The front of the bag usually features a happy animal, the brand name and the main benefit: grain-free, high protein, for puppies, for senior cats. The back carries the detail that careful owners read: ingredients, analytical constituents, feeding guidelines and any statutory information your product needs. That content is your responsibility, and we print it exactly as supplied.

Feeding guides are easier to follow as a simple table by weight. A clear panel or a die-cut window showing the kibble or treat shape builds trust. Matt finishes look natural and premium; gloss finishes make photography pop. Many pet brands use a soft-touch finish with spot gloss on the animal image to draw attention. Matt, gloss and spot finishes on film are compared in the print and finish options guide.

Small Brands and Growing Ranges

Many pet food brands start small, selling homemade treats at markets or online before moving into shops. Low minimums let you order printed bags for a single product and add more as your range grows. A consistent design system, with one layout and a changing colour for each flavour, keeps costs down and makes the range look professional from the start.

If you sell through pet shops, ask about bag sizes that fit standard shelf depths and peg hooks. A bag that fits neatly is easier for a buyer to say yes to.

Markets and agricultural shows are a good testing ground. A small run of printed treat pouches on a stall tells you quickly which flavours and sizes sell, and the feedback from owners standing in front of you is worth more than any guess made at a desk. Pet shops that carry live animals pair the treats with cardboard pet carriers for small animals.

Fill a Sample Bag and Open It Thirty Times

Pet food bags live or die on the zip, so test it the way an owner uses it. Fill a plain sample with your kibble to the weight you will sell, seal it, then open and close the zip thirty times with crumbs in the track. If the zip still shuts cleanly, the header depth is right; if crumbs jam it, ask for the zip set lower from the top seal. Weigh the fill that leaves the bag standing upright with a flat front, as that is the weight to print.

Send the product, the fill weight, the bag style, the closure, the artwork and any windows or handles, and a custom quote comes by email within one working day, with prices from £0.25 a bag and low minimums quoted per job. The free proof shows every panel before printing. Bags are made in 4 to 7 working days after approval and delivered free and tracked to UK mainland addresses in 2 to 3 working days; a batch that arrives misprinted or damaged is reprinted or refunded if reported within 10 days. Sacks above 2 kg move to the large mylar bags for bulk kibble.
