Food safety seals are security labels designed to indicate if a food package has been opened or tampered with. Once applied, they are difficult to remove or reseal without leaving visible damage, ensuring product integrity and customer confidence.
They’re widely used in:
✔️Takeout and delivery packaging
✔️Jars and bottles (sauces, honey, drinks)
✔️Meal kits and prep boxes
✔️Catering and retail food trays
✔️Tamper-sensitive or high-value food items
| Type | Function |
|---|---|
| Cap seal (partial wrap) | Breaks when bottle/jar is opened |
| Lid seal (flat flap) | Applied across the lid and side of a container |
| Box flap label | Secures paper or plastic food boxes |
| Tamper-cut label | Pre-slit to tear easily when lifted |
| Freezer-safe seal | For chilled or frozen food packaging |
We can produce these in custom shapes, clear or printed, and in sets with your main label if needed.
We select materials that perform well under real food service conditions:
Face Materials:
✔️PET film – Durable, tear-resistant, suitable for cold and moist surfaces
✔️PP film – Good clarity and flexibility
✔️Writable paper – For adding time, date, or initials
✔️Clear film – For minimal design impact
Adhesives:
✔️Permanent adhesive – For secure, non-removable seals
✔️Freezer-grade adhesive – Maintains adhesion in cold or frozen environments
✔️Tamper adhesive – Distorts film or leaves residue when removed
All adhesives are food-safe for indirect contact (applied to the outer packaging).
✔️Custom shapes to match your lid, box, or flap
✔️Branding, QR code, or product name printing
✔️Tear lines or pre-cut slits for easy breakage
✔️Transparent or opaque finish
✔️Optional writable area for date/time or initials
We support color-matched security seals that align with your branding while providing safety assurance.
✔️Delivery meals and takeout containers
✔️Honey jars, jam, or drinks
✔️Frozen meals and sealed trays
✔️Gourmet or high-value retail food
✔️Event catering and boxed lunches
