Does a film face make a label waterproof?

No. UPM describes its film faces as moisture resistant and describes wet service together with the adhesive. Whitlam lists water resistance among adhesive properties. Record the water exposure and leave the result empty until that construction is tested on the container.

Is a laminate the same as a release liner?

No. Whitlam describes a laminate as a protective film fused to the label, and a liner as the backing that carries the label and protects the adhesive until the label is applied. Choosing an overcoat does not choose the liner.

Are vinyl labels a third material beside paper and film?

No. Vinyl is a synthetic face, so it sits on the film side of this comparison. UPM's film page names PE, PP and PET, not vinyl. Whitlam describes static cling as a vinyl face with no pressure-sensitive adhesive, which is a different construction. A vinyl sample still needs its own adhesive and overcoat lines.

Paper vs Film Labels: Choosing the Face Stock

A paper face on a wet or tightly curved container can fail in use, and a film face still needs an adhesive and overcoat check on the same pack. This page shortlists a paper face or a film face for water, scuff, container curve and the print method, and it leaves the adhesive and the overcoat unchecked.

Use the condition you can already name, and leave every result cell blank until a sample is tested. On a squeezable container, UPM describes PE film as the face that flexes with the container, and states that PP film is generally not the face for highly squeezable packs. On a rigid container that meets moisture, UPM describes PP film as dimensionally stable when the adhesive is matched to that use. Where scuffing is the risk, UPM describes PET film for abrasion, and Whitlam assigns handling abrasion to a laminate, which is an overcoat. Where the pack is flat and dry and the ink is a metallic or fluorescent water-based ink, Whitlam’s notes point to paper as the first face to sample. These are supplier descriptions from the pages cited below. They are not adhesion numbers, and they do not select the adhesive or the overcoat.

Condition already named	Face to sample first	Still unchecked
Squeezable container or repeated flex	PE film, as UPM describes it	Adhesive and overcoat
Rigid container, moisture expected	PP film, with the adhesive named separately	Adhesive and overcoat
Scuff or abrasion is the main risk	PET film as the face, plus a varnish or laminate as the overcoat	Both result cells
Flat, dry pack; metallic or fluorescent water-based ink	Paper face	Adhesive, and an overcoat if scuff shows up later
UV print on film, or inkjet on film	Film face whose topcoat matches that press	Topcoat name and adhesive

The everyday words “plastic labels” and “film labels” point at the same kind of face on this page: a synthetic sheet, as opposed to paper. Vinyl is one synthetic. It is not given a separate grade here.

Face, adhesive and overcoat: a role note

The face is the sheet you are choosing. It is not the whole label.

Whitlam’s labeling fundamentals page separates the layers by job. Paper is a natural product made from wood or pulp. Film is a synthetic or plastic material. A varnish is a coating applied for a protective gloss. A laminate is a protective film fused to the label; Whitlam states that lamination can provide resistance to handling abrasion and chemicals. The adhesive is specified on its own list, which includes water resistance, humidity resistance and application temperature. The release liner is different again: Whitlam describes it as the support that carries the product through manufacturing and protects the adhesive until application.

Layer	Its job	What a face shortlist does not settle
Face (facestock)	Paper or film that carries the print. Shortlist it for curve, water, scuff and press.	Whether the label stays on, and whether the print needs an overcoat
Adhesive	Holds the label on the container. Water and humidity resistance are specified here.	The grade. This page does not choose it.
Overcoat	Varnish or laminate over the print. Whitlam ties handling abrasion and chemical resistance to the laminate.	Whether you need one. A film face does not answer that.

A liner protects the adhesive until the label is applied. It is not an overcoat, and it is not a face.

Takeaway: Write three lines before you compare samples: face, adhesive, overcoat.

Which face matches the container curve?

UPM’s film label materials page, read on 13 October 2026, describes three film faces by how the container moves.

PE (polyethylene) film is described as flexing with squeezable tubes, bottles and flexible pouches, and as conforming under repeated deformation without cracking, lifting or losing print quality. That sentence is UPM’s description of its PE films.

PP (polypropylene) film is described as dimensionally stable on rigid containers, in white, clear or metallized finishes. UPM states that PP films are generally not recommended for highly squeezable packaging because the material is stiffer.

PET (polyester) film is described for sustained chemical exposure, high-temperature processing, abrasion and industrial environments. The page gives no abrasion rating, so this comparison adds none.

Avery Dennison’s film category page splits films by shape rather than by resin. Conformable films are presented for packaging shapes that are hard for a label to follow. Rigid films are presented for a no-label look and for high-speed dispensing. A tight curve is a reason to ask which of those two a film sample is. It is not a reason to treat every film as conformable.

Paper, on Whitlam’s definition, is the wood-pulp face. No radius for paper wrinkling appears in the sources read for this page. If the container is squeezed in use, do not make paper the only sample. If the container is flat, keep paper on the list.

Takeaway: Mark the curve as flat, rigid-curved or squeezable, then shortlist PE, PP, PET or paper from those lines.

When does water change the face, and when does it change the adhesive?

UPM describes its film label materials as moisture resistant. For food and beverage it describes PP films, paired with an adhesive system suited to the use, as maintaining adhesion and print clarity in cold-chain and high-humidity environments. For clear film on glass, PET or HDPE, UPM says a clear-on-clear construction keeps the transparent look through condensation, refrigeration and ice-bucket conditions, and it attributes that to the adhesion system as well as the clear face.

Whitlam puts water resistance and humidity resistance on the adhesive property list, not on the face-material list.

A wet pack is therefore two entries. The face entry shortlists a film. The adhesive entry stays open. A film face is not a finished waterproof label, and this page states no immersion time, temperature or peel value.

Common mistake: Reading a moisture-resistant face as proof that the label will stay down on a wet or cold container. UPM’s clear-on-clear note names the adhesion system in the same breath as the face.

Takeaway: If the pack gets wet, shortlist a film face and leave the adhesive result empty until that construction is tried on the wet container.

What should you specify when scuffing is the risk?

Two layers are described as abrasion barriers, and this page does not treat them as substitutes.

UPM describes PET film as the face in its range aimed at abrasion, together with chemical exposure and high-temperature processing. It publishes no scuff-cycle count on the page read here.

Whitlam describes a laminate as a protective film fused to the label for resistance to handling abrasion and chemicals, and a varnish as a coating for a protective gloss. That laminate is an overcoat. It is not the release liner.

If scuff is on the brief, the sample record needs a face line and an overcoat line. Writing “PET” does not fill “laminate” or “varnish”.

Takeaway: Specify the face and the overcoat separately, and leave both results empty until the same sample is handled the way the pack will be handled.

Which print method fits which face?

Whitlam’s ink notes on the same page are the print constraint used here.

Water-based metallic and fluorescent inks are described as mainly used on paper. UV inks are described as usable on paper or film, and as needing a topcoat for UV. Solvent inks are described as a durable choice on films, including films that are not topcoated.

Avery Dennison describes TC-2000 as a film topcoat with UV inkjet printability and improved ink anchorage. That is one named topcoat, not a rule that every film must carry that product.

UPM states that its film materials are made for flexographic, offset and digital printing, including inkjet where the construction applies, and that each construction has its own technical sheet. Match the press to the sheet for that face. A film does not inherit the press setup used for paper.

Editorial shortlist, not a press trial: for metallic or fluorescent water-based ink on a flat, dry pack, sample paper first. For UV or inkjet on film, name the topcoat before you treat the face as printable.

Takeaway: Write the print method and the topcoat on the record. A face name without that line is not a print decision.

Sample test record

Copy the rows. Leave the result column empty. This page has no trial to enter.

What to record	Result
Container material and shape
Curve: flat, rigid-curved, or squeezable
Water or humidity the filled pack will meet
Scuff or handling the pack will meet
Print method
Topcoat, if the press needs one
Face sample: paper, PE, PP, PET, or conformable versus rigid film
Adhesive still to check
Overcoat still to check: none, varnish, or laminate
What the face did
What the adhesive did
What the print and overcoat did

Takeaway: The record is finished only when the result cells are filled from the sample, not from this page.

What this page does not decide

Adhesive grade is out of scope. Whitlam describes a permanent adhesive as one that usually cannot be removed without damage to the label or the surface, and a removable adhesive as one that typically lifts without leaving residue. It also notes that time or extreme exposure can turn a removable adhesive permanent. Those definitions show why the grade is its own check. They are not a selection.

Where the adhesive comes from is also a different decision. Pressure-sensitive and wet-glue labels compare a label that arrives with adhesive on a liner and a paper label that is glued on the machine. The labels section sets those application routes beside sleeves and in-mould labels.

Recycling is out of scope as a verdict. UPM states that wash-off adhesive constructions are available for labeled PET bottles and for PE or PP containers aimed at a recycling stream. That statement is not used here as a certification, and paper is not ranked against film for recovery.

Compliance marks, food-contact claims and any UL or CSA construction are also out of scope. Whitlam names those categories; this page does not assign them to a face.

Takeaway: Stop when the face is shortlisted and the adhesive and overcoat lines are still open.

How this comparison was assembled

The shortlist is compiled from three public supplier pages, not from a trial run for this article. UPM’s PE, PP and PET descriptions, including the squeezable-pack note and the moisture notes, come from its film label materials page on 13 October 2026. Whitlam’s definitions of paper, film, varnish, laminate, adhesive properties and ink families come from its label characteristics page, retrieved 11 October 2026. Avery Dennison’s conformable films, rigid films and TC-2000 topcoat note come from its film category page, retrieved the same day. No peel strength, scuff cycles, immersion hours or certification numbers are added. The result column stays empty so a later sample test is not confused with these descriptions.
