EcoEnclose Sustainable Packaging Reinforced Kraft Paper Water-Activated Tape

Good

Lower concern. Gummed tape typically uses starch adhesive, not PFAS.

Verdict · BuyGummed kraft tape poses minimal chemical hazard; water-activated adhesive avoids synthetic polymer concerns. Good choice for food contact.

Water-activated kraft paper tape uses starch-based adhesives instead of fluorinated coatings, making it inherently lower PFAS risk. Product design suggests minimal PFAS likelihood.

⚠️

Bleach residues or chlorine compounds in kraft paper

If the kraft paper is bleached (as opposed to unbleached), residual chlorine or chlorine dioxide may be present at trace levels; unbleached kraft presents lower concern for direct food contact, though bleached kraft is also FDA-approved for packaging.

70/ 100
⚠️

Bacterial or mold growth on gummed surface

Starch-based adhesives can support microbial growth if stored in humid conditions before use; proper dry storage prevents this, but deteriorated or aged rolls may become colonized if exposed to moisture.

Microplastics

Kraft paper and gummed adhesive are cellulose-based and do not shed synthetic microplastics; this hazard is not applicable to water-activated tape formulations.

The full breakdown

What it's made of and why it matters

This product is kraft paper (unbleached or minimally bleached cellulose) coated with a water-activated gummed adhesive, typically starch-based with natural gum binders like dextrin or guar. Unlike synthetic hot-melt or pressure-sensitive tapes, gummed adhesives do not rely on synthetic polymers, plasticizers, or volatile organic compounds. Kraft paper itself is approved by the FDA for food contact when used as a sealing material and does not leach into contents under normal storage conditions.

The brand's record and disclosure

Sealing Strip's public materials position this product under an 'EcoEnclose' sustainability label, suggesting transparency intent, but specific safety certifications (FDA food-contact clearance, ISO testing) are not documented in widely available sources. The brand's silence on PFAS is consistent with the product formulation (gummed tape rarely requires PFAS), but lack of explicit certification statements limits third-party verification. No recalls or safety controversies are on record for this product line.

How it compares in its category

Gummed kraft tape is a lower-chemical alternative to acrylic or rubber-based pressure-sensitive tapes, which can off-gas VOCs or contain plasticizers over time. It is functionally equivalent to other water-activated kraft tapes in the market and avoids the microplastic shedding risk of synthetic polymer tapes. Cost and storage (requires moisture activation) are minor practical trade-offs versus convenience of pre-moistened alternatives.

If you buy it

Store the tape roll in a cool, dry place; exposure to high humidity before use can reduce adhesive effectiveness. Upon application, the water activation sets within seconds; no special heat or equipment is required. Kraft paper and starch-based adhesive are compostable with food waste, making post-use disposal straightforward. Replace rolls if adhesive visibly hardens or becomes non-sticky due to age or storage conditions.
