Kraft Paper Laminated Bags — Paper Shelf Appeal With Film Performance Underneath
Kraft laminate solves a specific contradiction: consumers read paper as natural and premium, but paper alone cannot seal, barrier or survive the supply chain. Our kraft laminated structures bond kraft paper to a functional film layer — recycled PE or PP — so the pack looks like paper and performs like engineered packaging. The film layer can carry 30–100% PCR content under GRS certification, keeping the sustainability claim structural, not cosmetic.
Technical profile
Technical Profile — Typical Values
| Structure | Kraft paper / adhesive / PE or PP sealant film |
|---|---|
| Kraft paper weight | 40–80 g/m² (natural brown or white) |
| Film layer | 15–30 µm PE/PP; PCR content 30–100% available (GRS TE-00057717) |
| Total thickness | 90–140 µm typical |
| Moisture barrier | Moderate to high (driven by film layer) |
| Grease resistance | Moderate — suitable for dry and semi-greasy goods |
| Oxygen barrier | Low without added barrier layer |
| Heat-seal window | Set by sealant film (PE: 110–150 °C; PP: 130–165 °C) |
| Printability | Excellent — natural kraft base, up to 10 colours |
| Options | Clear windows, degassing valves, tin-tie, zipper |
Typical values — customizable to spec. Final parameters are confirmed against your product, filling line and test protocol.
Fit check
Where Kraft Paper Laminate Performs — and Where It Doesn't
Strong fits
- Gift and premium retail bags — the natural kraft surface elevates perceived value without rigid-box cost; see gift bag programmes.
- Coffee, tea, dry food and snacks — combined with zipper closures and optional valves; for oxygen-sensitive recipes we add a barrier layer or move to coex structures. See food packaging.
- Food-adjacent and takeaway packaging — grease tolerance for baked and dry goods.
- Branded e-commerce packaging — paper outside for unboxing feel, film inside for moisture protection; see branded packaging.
Honest limitations
— Not fully plastic-free: the sealant film is essential to function. We state this plainly so your claims team can word the pack correctly ("paper-based laminate with recycled film layer").
— Not suitable for liquid fill or retort; for those, use multi-layer coex.
— High-humidity warehousing can affect the paper layer over long periods — specify film weight accordingly.
Evidence
Sustainability Position — Stated Precisely
- Film layer with 30–100% PCR content, certified under GRS Scope Certificate TE-00057717 (Textile Exchange portal verifiable)
- Substituting 1 t of virgin PE with recycled content avoids roughly 2.6 t CO₂e (industry estimate)
- Documentation aligned to EU PPWR 2030/2040 reporting and UK packaging rules
- If your claim requires industrial compostability rather than recycled content, evaluate our PLA option — we will tell you honestly which claim survives scrutiny in your market

Frequently Asked Questions
No — and we advise against it. The film layer is what makes the bag sealable and moisture-resistant. The accurate claim is a paper-based laminate, optionally with certified recycled content in the film layer. We help your compliance team word claims that survive UK and EU green-claims scrutiny.
Yes. Clear film windows, press-to-close zippers, tin-ties and degassing valves are all standard converting options. Window placement affects the barrier locally — our engineers will flag any shelf-life implication before production.
