ULINE Reinforced Kraft Tape
Skip. Undisclosed water-resistant coating suggests possible PFAS use.
This reinforced kraft tape has water-resistant properties common in grease-resistant food packaging. The manufacturer discloses nothing about coating chemistry or PFAS content.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Water-resistant kraft tape coatings often use PFAS for repellency. Sealing Strip does not disclose coating type. If PFAS is present and tape contacts food or is heated, migration risk exists; this is the primary reason for PFAS skip-grade.
Source, ATSDR ↗Coating degradation and particle shedding
Water-resistant coatings can crack, peel, or shed microparticles under stress or aging. If tape is used on food surfaces and coating degrades, small fragments could contaminate product; frequency and extent unknown.
What’s reassuring
Synthetic adhesive composition and migration
Kraft tape adhesives are typically rubber or acrylic based and food-contact approved when formulated to FDA standards. No reported contamination issues exist for this brand, but unlabeled adhesive composition prevents full confidence.
Solvent residues in adhesive or coating
Adhesive and coating application may involve volatile solvents (toluene, heptane) that offgas during manufacture and early storage. No public complaints recorded; risk is low after curing but present in new rolls in sealed storage.
Mold or bacterial growth on tape surface
Kraft paper with moisture exposure can support mold, especially if water-resistant coating is compromised. Storage in humid conditions increases risk; this is a use-phase hazard rather than manufacturing issue.
The full breakdown
What it's made of and why it matters
ULINE Reinforced Kraft Tape is kraft paper (cellulose fiber) with a synthetic adhesive layer and an unspecified water-resistant topcoat. The water resistance is the concern, manufacturers typically achieve this via fluorinated compounds (PFAS) or silicones, but Sealing Strip's formulation is not publicly disclosed. Kraft paper itself is food-safe when uncoated, but the adhesive and coating chemistry determine actual safety for food contact.
The brand's record and disclosure
ULINE (parent company) has no published PFAS transparency policy or third-party certifications specific to this product line. Sealing Strip brand materials do not disclose adhesive or coating composition. No recalls linked to this tape are on record. The silence on water-resistance mechanism is the primary red flag for responsible sourcing assessment.
How it compares in its category
Kraft tape is a lower-risk sealing option than PVC or plastic-film tapes for general use. However, reinforced kraft with undisclosed coatings sits midway, better than fully synthetic tapes, worse than certified water-resistant kraft options (e.g., kraft tapes with explicit silicone or certified PFAS-free water barriers). Most competitors similarly lack disclosure, making this typical rather than distinguished.
If you buy it
Use for non-food-contact sealing (shipping boxes, document storage). Do not use directly on food or food-contact surfaces without a barrier layer. Store in cool, dry conditions; adhesive can degrade or off-gas in high heat (avoid >60C environments). Replace tape if adhesive becomes sticky or coating shows visible wear. For food packaging, choose certified water-resistant kraft or uncoated kraft alternatives with transparent adhesive sourcing.
