Pet Oral Dissolvable Films: Format Guide

Dissolvable film is the newest supplement format in the pet market and the one that solves the category's oldest problem: animals that refuse to take anything. There is no chew, no tablet and no measuring — the film goes in the mouth and disappears. The trade-off is payload, and understanding that limit is what keeps expectations honest.

What the format is

An oral film is a thin, flexible strip of a film-forming polymer carrying the actives. It is placed in the mouth, where it hydrates with saliva and dissolves within seconds. In human products the same technology is used for breath strips and fast-dissolving medication; in pets it solves a delivery problem rather than a bioavailability one.

Three polymer families dominate: pullulan, which is natural, quick-dissolving and has good mouthfeel; HPMC, which is more robust and often used where higher active loads are needed; and starch-based systems, which are cheaper but more prone to brittleness. The choice affects dissolution speed, tensile strength and how much active can be carried without the film breaking.

How the film is made

Production is a coating process rather than a compressing or cooking one, which is why it treats actives more gently than a soft chew:

  1. Prepare a slurry. Film former, plasticiser, actives and any flavour are dispersed in water to a controlled viscosity.
  2. Cast the film. The slurry is coated onto a moving liner at a defined wet thickness — the step that determines final film weight and dose uniformity.
  3. Dry. Controlled-temperature drying removes water without the prolonged heat a soft chew matrix requires.
  4. Cut and individualise. The film is slit and cut into unit doses; cut accuracy is dose accuracy.
  5. Pack. Films are fragile once cut and need a laminate sachet that protects against moisture and light.

The important consequence for buyers is that the low-temperature route preserves actives that a cooked chew would degrade — which makes film attractive for botanicals, probiotics and oil-based ingredients that struggle in soft chews.

The limit that defines the format: payload per unit

A film is thin. The area and thickness that an animal will tolerate comfortably bound how much material one unit can carry, and bulky actives such as glucosamine, chondroitin or a full mineral premix will not fit. This is why film-based products in the pet market tend to be focused formulations — a single function with a small active list — rather than broad multi-ingredient blends.

SpecificationWhy it decides the product
Film thickness and weight uniformityControls dose consistency unit to unit
Disintegration timeWhether the claim "dissolves in seconds" is true in practice
Moisture contentBrittleness, sticking and microbial stability
Active content uniformityProves the coating and cutting steps are controlled
Tensile strengthWhether the film survives handling and packaging without tearing

Why cats and difficult animals are the core market

Film converts the hardest compliance problem in the category into something closer to a non-event. Cats that refuse chews and tablets, dogs that spit out medication, and animals with oral discomfort all take a film more readily. There is also a handling advantage: no measuring, no tablet that is dropped on the floor, no crumbs in a food bowl.

That said, the format is not universally accepted. Some animals dislike the sensation of a film in the mouth, and film is impractical for products requiring a large daily dose. Where acceptance is the deciding factor, it is worth testing the format on a small panel before committing to tooling and packaging.

Where film fits commercially

Film performs where convenience and compliance outweigh the payload constraint: focused formulas for cats, senior animals, dental and freshness positioning, and products where rapid intake matters. It also carries a novelty advantage in retail, though the format's reputation depends on the dissolution and handling experience actually matching the promise on the pack. A film that sticks to the palate or tears in the sachet damages the whole category's credibility with that owner.

Our film-format range includes a dental care oral dissolvable film, a heart care oral dissolvable film and a parasite care oral dissolvable film. The format category is described under pet oral dissolvable films.

Questions buyers ask us

Can a film replace a chew for dental products?

For freshness positioning, yes. For mechanical cleaning, no — a film has no abrasion effect, and the claim set should reflect that.

Why can't we put a full joint formula in a film?

Because glucosamine and chondroitin are bulky and a comfortable unit dose of film cannot carry them. Multi-active blends generally belong in a powder, tablet or chew.

What do you need to quote a film product?

Actives and level per unit, target species, unit dimensions, units per day, sachet presentation and expected order volume.
