A candle brand has chosen natural brown kraft packaging as part of its sustainability agenda. The boxes are pretty, they’re robust and they’re in keeping with the brand. The catch is that they’ve applied a protective coating to the boxes to prevent staining and moisture damage. The issue is whether the boxes can then be recycled.
The answer is down to the make-up of the coating, how it’s applied and whether the end product can be processed by the recycling facilities.
For brands looking at kraft candle boxes the issue of sustainable packaging material isn’t simply about picking recycled paperboard. The challenge is in protecting the box whilst at the same time maintaining its recyclability.
Why do Kraft candle boxes need protective coatings?
Uncoated kraft paperboard has a very porous surface and will absorb moisture and oils. A properly sealed candle jar should prevent any wax or fragrance from leaking out, but the packaging itself can still be subject to residue, condensation and handling damage.
Protective coatings on kraft paperboard can help in this respect.
A candle brand selling heavily scented candles might be looking for additional stain resistance. Another brand, selling their candles through warehouses that are quite humid, would be looking for moisture resistance.
The problem is that coatings alter the behaviour of paperboard in the recycle stream. A finish that gives you better surface protection may also make fibre recovery more difficult.
That makes coating selection a key manufacturing decision, especially in the case of sustainable candle ranges.
Wax Coatings vs. Plastic Laminations vs. Water-Based Coatings
Not all protective finishes are created equal in terms of performance or recyclability.
| Coating type | Main purpose | Recycling consideration |
| Wax coatings | Moisture and grease resistance | Can interfere with conventional paper recycling |
| Plastic lamination | Surface protection, moisture resistance, and durability | Plastic layers may complicate fiber separation |
| Water-based barrier coatings | Formulation-dependent moisture, oil, or scuff resistance | Some are compatible with recycling, but testing is necessary |
| Uncoated kraft | Natural appearance and easier fiber access | Usually simpler to recycle when clean and otherwise compatible |
Wax-Coated Kraft Packaging
Wax coatings create a moisture-resistant surface which can help to limit the ingress of liquid.
However, conventional wax treatments can be problematic in terms of repulping, especially when the coating interferes with fibre separation or screening.
Brands looking at wax-coated kraft packaging should check that it’s compatible with their recycling stream prior to making any recyclability claims.
Plastic-Laminated Candle Boxes
Plastic lamination will protect your printed design against moisture, scuffs and handling.
The problem arises during recycling. The plastic laminates can prevent water from getting to the paper fibres effectively, which makes the separation more of a problem.
Double sided lamination can add an extra layer of processing difficulty.
For candle brands that are looking at recyclable candle box materials lamination should be considered in terms of the existing recycling infrastructure rather than just for its durability.
Water-Based Barrier Coatings
Water-based barrier coatings are increasingly being looked at as an alternative to the traditional plastic lamination.
Some formulations give you useful surface resistance and at the same time allow the paper fibres to be recovered.
However, water-based doesn’t necessarily mean plastic-free, biodegradable or recyclable. Some formulations contain polymers which can have an impact on recyclability.
Industry recycling guidance recommends that coated paper products be assessed via appropriate testing rather than simply by the name of the coating.
How Protective Coatings Affect Kraft Candle Packaging Recyclability
The major technical issue is repulpability.
Repulpability is the measure of how well the paperboard will break down in water so that the fibres can be recovered for use in the manufacture of new paper products.
During recycling, the coatings can interfere with fibre separation, reduce the amount of material that is actually recyclable and/or create some undesirable residues.
According to How2Recycle, packaging assessments may require information on coating chemistry, application coverage, additives and lamination. Packaging that is based on special fibres may also require recyclability testing.
For the candle manufacturer, it means asking for evidence of the full package construction (printing and finishing included) rather than just assessing the original kraft sheet.
What are the recycling requirements for candle packaging & cardboard box manufacturers USA?
The US Federal Trade Commission’s Green Guides guide environmental marketing claims.
Under the guidance, unqualified recyclable claims will in general, require that appropriate recycling facilities be available to at least 60% of the consumers or communities where the packaging is sold. Otherwise qualifications are required.
This is important when businesses are advertising their custom cardboard cartons as fully recyclable.
Custom cardboard cartons are a symbol of natural brown appearance. Whether the finished coated carton passes the requisite recycling assessments.
If consumers can get access to appropriate collection facilities. Whether the windows, the liners and all the other bits and pieces need to be disposed of separately. If the environmental claims actually do describe the finished packaging. A specific verifiable claim is far more useful than a general statement about being ‘green’.A specific verifiable claim is far more useful than a general statement about being environmentally friendly.
How Can Think of a candle manufacturer selling glass jar candles via retail and through online subscription.
The brand needs custom cardboard cartons that will protect the printed surfaces without creating any undue complications from a recycling point of view.itA practical selection process starts with three questions.ti1. What protection does the candle actually need?.
Look for likely exposure to moisture, fragrance residue and surface abrasion. A boxed sealed glass candle won’t necessarily require the same barrier treatment as packaging which is in direct contact with oils. i.e., don’t specify heavy-duty coatings unless there’s a very clear reason for doing so.av2. Has the finished packaging been tested? Request the relevant documentation on coating composition, resistance and recyclability.
Where appropriate, finished samples were tested under the conditions of expected storage and handling.pl3. Can the design use less coating? At other times, protection can be achieved through better inserts, better primary containers or better carton construction. Reducing the amount of coating coverage may be a simple way of simplifying the package design without compromising on protection. The packaging design without sacrificing protection.
Why Supplier Selection Matters for Sustainable Candle Packaging
When you’re looking at cardboard box manufacturers USA, candle businesses should look beyond the quality of the print and the wholesale price.
Suppliers should be able to talk through paperboard specs, coating options, sample evaluation and the appropriate packaging construction.
At Multiple Packages businesses can look at custom cardboard cartons, beauty, retail and a whole host of other product types.
Its standard candle boxes provide a good basis on which to look at kraft, carton sizes, inserts and the specific printing requirements of the brand.
For smaller candle businesses Low MOQ ordering can also be used to support controlled packaging launches, helping the brand to avoid committing to large quantities prior to finalising material and artwork.
Frequently Asked Questions
What’s the minimum order quantity for the sustainable kraft candle boxes?
Low MOQs may be possible depending on the carton structure, material and finish. Just confirm the MOQ for your particular requirements.
How long does it take to produce the custom cardboard cartons?
Production is dependent on order quantity, artwork approval and coating. Always get a confirmed schedule before you place an order.
Can I get a sample before placing an order for the coated kraft candle packaging?
Talk to the supplier about sample availability so that you can assess the surface protection, the printing and the material itself before going into bulk production.
Choose Protection Without Overlooking Recyclability
Sustainable candle packaging requires a lot of thought when it comes to the materials you use, the coatings you apply and the end of life scenario.
Before you go ahead and order the kraft candle boxes, make sure you’ve considered whether any protective finishes are required, ask for the relevant test data and confirm that the recycling claims can be substantiated.
Multiple Packages can help businesses explore brand-focused packaging options that balance presentation, protection, and practical production needs.
