ProLine Self-Adhesive Kraft Paper Carton Box Sealing Packing Tape
Skip until coating and adhesive ingredients are disclosed.
This self-adhesive packing tape contains undisclosed coatings and adhesive formulations. Water and grease resistance point to possible PFAS treatment with no public ingredient information.

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.
Adhesive composition (unspecified synthetic or acrylic)
Self-adhesive tapes may contain residual solvents, plasticizers, or tackifiers; without ingredient disclosure from Sealing Strip, potential for low-level migration to food packaging surfaces cannot be ruled out, though risk is low under normal room-temperature storage.
Water-resistant coating (likely wax, clay, or undisclosed)
The coating formulation is not disclosed; if PFAS-based (reviewed separately) or silicone-based, trace migration into food contact surfaces is theoretically possible. Even wax or clay coatings may contain processing contaminants if supplier standards are unknown.
What’s reassuring
Heavy metals
Kraft paper tape typically contains minimal pigmentation, and acrylic adhesives do not commonly accumulate heavy metals. No recalls or public warnings for Sealing Strip brand on this hazard are on record.
Source, FDA ↗Formaldehyde / VOCs
Kraft paper itself is not treated with formaldehyde resins; however, synthetic adhesives or water-resistant coatings could theoretically contain formaldehyde releasers if low-cost formulations are used. Sealing Strip provides no specification to confirm absence.
Source, ATSDR ↗Microplastic or adhesive particle shedding into food
Kraft paper is biodegradable and does not shed microplastics. Acrylic adhesives do not fragment under normal use. Risk is only relevant if tape is mechanically damaged or heated above design limits, releasing adhesive particles.
The full breakdown
What it's made of and why it matters
ProLine's tape consists of kraft paper (wood pulp, naturally low-toxicity) with a self-adhesive layer stated as acrylic or synthetic adhesive, plus an undisclosed water-resistant coating. Kraft paper itself does not leach harmful chemicals into food under normal conditions. However, the adhesive and coating formulations are critical, acrylic adhesives show lower concern, but synthetic adhesives may contain solvents or plasticizers; water-resistant coatings commonly use wax, clay, or PFAS compounds, and the brand has not disclosed which. Without ingredient transparency, the risk profile cannot be fully assessed.
The brand's record and disclosure
Sealing Strip brand maintains a silent posture on adhesive composition, food-safety certifications, and coating ingredients, no published safety data sheets, third-party testing, or NSF/FDA approval statements are on record. The brand does not publicly commit to PFAS avoidance, formaldehyde limits, or heavy-metal testing in adhesives or coatings. This lack of disclosure is the primary concern and indicates a lower compliance or transparency standard relative to major tape manufacturers (e.g., 3M, Shurtape) that publish technical specifications.
How it compares in its category
Kraft paper packing tape shows lower concern than PVC or polyester tapes for food contact because paper is inert. However, this product's advantage is undermined by the unknown adhesive and coating chemistry. Competitors like Shurtape and 3M offer food-safe, certified versions with disclosed adhesive types and published migration testing; Sealing Strip offers neither. For non-food industrial sealing, this tape poses minimal risk; for repeated direct food-box contact, certified alternatives are preferable.
If you buy it
Use this tape only on the exterior of food boxes, not in direct contact with food or food-contact surfaces. Avoid prolonged heat exposure (above 60°C/140°F), as synthetic adhesives may soften or off-gas. Replace if adhesive yellows, hardens, or loses tackiness, indicating aging of unknown chemical components. For sensitive food applications (organic, allergen-free, export-regulated), source a certified food-safe tape instead to eliminate guesswork.
