Compare PET cabinet doors as complete panels: the specified PET face and finish, the core, the reverse-face construction, the bond and the finished edges. Then examine any later cuts or holes and the care instructions for that exact product. “PET” identifies a material family; it does not establish that every offered door has the same appearance, emissions, scratch resistance or moisture performance.
The sample record below completes a material decision. A buyer rejects an exposed-core submission, requires a factory-made replacement and accepts the revised PET/MDF construction and visual sample. Unsupported performance claims are removed from the accepted specification.
Confirm that the offered surface is actually PET
PET means polyethylene terephthalate. Ask for the manufacturer, product family, finish and component references behind the seller’s description. A lacquered board, an acrylic-faced board and a PET-faced board should not be grouped under the same surface identity because they look similar in a photograph.
A real example is EGR’s PETLite. Its February 2024 technical data sheet describes PET skins laminated to MDF with PUR adhesive and a two-sided construction. The current EGR product page also identifies PET film, MDF, PUR lamination and matching edge materials. This establishes an identifiable PET system; it does not make PETLite’s documentation applicable to an unrelated supplier’s panel.
Separate a finished board from a loose decorative laminate. PETLite’s sheet distinguishes film on its factory panels from its thicker loose laminate for manual lamination. A specification copied from one format does not automatically describe the other. The P-42 record later in this article is a separate submission, not a PETLite sample.
Read the construction from the face to the reverse
Request a layer-and-component record with each item tied to the offered panel:
- Face: PET product, decor, finish, any coating and protective film. The removable shipping protection is not the permanent decorative surface.
- Core: manufacturer, panel product/grade, thickness and the relevant application and emissions documents.
- Reverse: actual backing material and finish, with confirmation that it belongs to the declared panel construction.
- Face bond: the lamination system and fabricator’s applicable processing instructions.
- Edge: tape identity, thickness/profile, adhesive system and the process used on the finished door.
- Secondary work: final sizing, hardware holes, notches or other cuts, with an approved treatment where the actual system requires one.
Do not call a panel balanced merely because both faces have a similar color. Identify what is on the reverse and the manufacturer’s construction requirements. Changing the backer or applying a different face build-up creates a configuration to review; an attractive front sample alone cannot settle that question.
The face bond and edge bond are also different interfaces. A product sheet describing PUR between PET film and MDF is not evidence that the door maker used the correct edge tape, prepared the edge properly or achieved a continuous edge joint. Obtain the relevant processing record for each interface.
Inspect the face, finished edge and separate core sample as distinct parts of the door review.
Examine the edge and any work performed after edging
Look at the completed bottom edge, corners and transitions between the face and tape. Record visible gaps, lifting, exposed core, adhesive residue or a mismatch that the buyer does not accept. Describe the actual observation and location instead of reporting a generic “waterproof edge” verdict.
For its own system, PETLite’s technical sheet describes preprimed ABS edge band and recommends PUR application on an automatic edgebander. That is a specific processing example, not a rule that any ABS/PUR combination makes any PET/MDF door watertight. The panel, tape, preparation and process still need to match the offered system.
Check whether a site modification would cut through an already finished edge. A shortened door with newly exposed MDF is different from the approved factory-edged sample. Have the maker resolve the final size and applicable edge treatment before accepting that change. Do not prescribe filling every hinge cup or screw hole with sealant: material and hardware instructions must govern those details, including their fit.
P-42: reject, revise and accept a defined sample
Assume an October 30, 2026 review of nominal 18 mm PET-on-MDF doors for ordinary vertical cabinet fronts in a dry interior. The buyer wants a warm-gray matte face and an acceptable matching edge.
Submission A has a short visible opening at the bottom-edge joint. The maker has also trimmed a bottom edge after banding, leaving an uncovered core strip. The reverse material is not identified in the submission. The buyer rejects A as an approval sample and does not accept a promise to hide those conditions during installation.
The maker responds by producing the door to its final size in the workshop, replacing the affected edge work and returning a documented revision B. Its record identifies the face, MDF core, matching PET reverse, ABS tape and separate face/edge bond processes. It also withdraws unsupported “scratch-proof,” “heat-proof” and “no fingerprints” wording.
| Check | Submission / required response | Recorded outcome |
|---|---|---|
| PET face | Identify warm-gray matte PET face as F-42, including the supplier’s product/finish sheet. | Revision B identifies the face. Accept its material identity and selected appearance; no generic durability ranking. |
| Core | Identify dry-interior MDF product C-42 and the nominal finished-panel thickness on the part drawing. | Maker supplies the core and assembly references. Accept the specified core for this material brief; do not infer emissions from PET. |
| Reverse | A lacks a backing identity. Require the declared matching PET reverse and panel-construction record R-42. | B documents the reverse and unchanged face/core build-up. Accept that configuration; no substitution without review. |
| Lamination / edge | Separate face-bond record L-42 from ABS edge E-42 and the edge-processing record EB-42. | Maker confirms the specified PUR processes for this system. The records do not establish universal water resistance. |
| Bottom joint | A has a visible local gap and exposed core after trimming. Factory replacement requested. | B shows a continuous finished bottom edge in the stated visual review. Accept the corrected sample; no water or ageing test claimed. |
| Cuts / holes | No site shortening or added notch approved. Hardware drilling follows the actual part and hardware instructions. | Delete the proposed site-trim method. Any new cut or hardware change reopens its detail; no blanket sealant instruction. |
| Color / edge match | Compare the unprotected review piece and edge against master M-42 under the agreed project lighting. | The buyer accepts B’s face/edge relationship. No measured color-difference or finish-performance claim. |
| Care / claims | Obtain a finish-specific care sheet. Performance statements need evidence for the offered construction and conditions. | Accept care record CL-42; remove the three unsupported claims. Unproven properties are not approval criteria met. |
Completed decision: the buyer accepts revision B as the chosen PET door construction and visual reference, rejects submission A and deletes the site-trim proposal. The accepted order brief names F-42/C-42/R-42/E-42 and the processing/care records. It does not present the visual review as a lifetime bond, heat, scratch or water test.
Production still has to match that accepted configuration and any actual application requirements. Keep the corrected sample, document revision and photographs together. An unapproved core, backer, edge or processing change is a new submission rather than an invisible equivalent.
Approve the appearance you can actually observe
Use a dedicated review piece with its removable protection taken off in accordance with the supplier’s instructions. Comparing one protected face against one exposed edge can misrepresent the finished relationship. Keep production protection and handling instructions separate from the review-piece procedure.
Record the face and edge decor references, sample and batch identifiers, viewing conditions and the buyer’s decision. A screen image or an edge code described as “matching” is not the completed visual approval.
If the desired appearance cannot be achieved with the offered PET system, request an actual acrylic alternative as a separate panel submission. Compare its own face/core/back/edge construction and care requirements. No PET-versus-acrylic scratch, heat or environmental ranking follows from the resin names alone.
Keep cleaning instructions attached to the selected finish
EGR’s current PETLite care guidance starts with a soft microfiber cloth and warm soapy water, and distinguishes additional care products for gloss and supermatte. It also warns against specified aggressive or abrasive cleaners. Follow the actual offered product’s instructions; this example is not permission to apply one maker’s cleaner to every PET face.
Distinguish routine care from a workshop adhesive-cleanup operation. A processing instruction for glue residue does not become a household maintenance instruction. Before adopting a cleaner, check the exact finish and any edge/bond restrictions, and use the manufacturer’s procedure rather than an improvised solvent test on the approved door.
The same discipline applies to claims. A report should identify the specimen, method, result, finish and relevant conditioning. A surface-film result is not automatically a finished-door result. Ask which evidence applies to the face, core, bond, edge or complete assembly. The PET label alone does not establish low emissions, whole-door recyclability, certification or service life.
Send NOVARMIA the face/finish reference, core and reverse specification, edge and cut details, approval sample record and intended cleaning/use conditions to discuss a cabinet-door package. Identify which properties are observed, documented or still awaiting applicable evidence.
FAQ
Can a damaged PET door be repaired like a painted door?
Ask the panel/door maker for the applicable repair method and the appearance it can achieve. Do not assume sanding or repainting will reproduce the original film finish. If no acceptable repair is available, agree replacement and the matching-sample process.
Can I mix leftover panels from different batches?
Identify and compare them before fabrication, including orientation, face and edge appearance. If mixed batches are acceptable, record where they will be used. A shared decor name alone is not the buyer’s approval of the combined installation.
Does an MDF emissions report cover the entire PET door?
Read the report’s specimen and scope. It may address the core rather than the bonded finished assembly. Request the evidence required for the actual supplied product and destination, and do not extend a core result to untested adhesives or construction by assumption.
What if the protective film becomes trapped behind hardware?
Resolve the removal sequence with the specific panel and hardware instructions before assembly. PETLite’s guidance, for example, identifies situations where protection needs removing around an interface. Do not pull it out in a way that disturbs installed hardware or the approved surface.
