Barrier Films & Multi-Layer Laminates South Africa
Advanced multi-layer laminate structures and barrier films engineered to protect your product's integrity, extend shelf life and meet the strictest food safety and pharmaceutical standards — manufactured in Germiston.
The right structure for every application
Flexweb manufactures a comprehensive range of multi-layer laminate structures in-house, combining printed or plain outer layers with barrier and sealant layers precisely matched to your product's shelf-life requirements, distribution channel and retail presentation needs.
Whether your challenge is moisture, odour, alcohol, atmosphere, UV or puncture resistance — our experienced team will specify the right structure and produce it to consistent, documented quality at our BRC and ISO-certified Germiston facility.
Available structures
- PET/PE — clear, metalized or high barrier · gas flushing, biltong, nuts, snacks
- PET/CPP — alcohol sachets, retort-compatible applications
- PE/PE — soap powder packaging, home care products, detergents
- PET/Alu/PE — high barrier food packaging, coffee bags, pharmaceutical sachets
- Paper/Alu/PE — soup packaging, pharmaceutical sachets, premium retail
- Recyclable — PET/PET, MDO/PE, PP/PP structures for EPR compliance
Barrier layers — materials and micron ranges
Our barrier layer selection covers every combination of moisture, oxygen, aroma, UV and alcohol barrier required for South African food, pharmaceutical and industrial packaging applications.
| Barrier material | Thickness range | Primary barrier function | Typical applications |
|---|---|---|---|
| Aluminium Foil | 6.35μ – 9μ | Oxygen, moisture, light, aroma — total barrier | Coffee bags, pharmaceutical sachets, soup packaging, premium food |
| Metalized PET | 12μ | Oxygen and moisture barrier with high clarity | Snack foods, biltong, nuts, confectionery |
| AIOX PET | 14μ | Transparent oxygen barrier (aluminium oxide coating) | Food products requiring product visibility with O₂ barrier |
| CPP (Cast Polypropylene) | 20μ – 70μ | Moisture barrier, heat-sealable, retort-compatible | Alcohol sachets, retort packaging, high-clarity applications |
| Metalized BOPP | 18μ | Moisture barrier with metallic finish | Confectionery, snacks, FMCG retail packaging |
| BOPA (Nylon) | 15μ | Oxygen barrier, puncture resistance, thermoformability | Vacuum packaging, thermoforming, meat and dairy |
| EVOH | 40μ – 70μ | Outstanding oxygen barrier (EVOH layer within co-ex structure) | Extended shelf-life food packaging, ambient products |
Sealant layer options
Our experienced team guides you in choosing the ideal sealant layer for your filling equipment, seal integrity requirements and cost target.
| Sealant material | Thickness range | Layer structure | Notes |
|---|---|---|---|
| LDPE / LLDPE / MDPE / HDPE / PVA / OPA blends | 25mic – 150mic | Single to 5-layer co-extrusion | Most versatile sealant option — matched to product and line requirements |
| CPP | 20mic – 70mic | Mono or laminated | High clarity, good hot-tack, retort-compatible grades available |
| BOPP | 18mic – 40mic | Mono or laminated | High stiffness, good moisture barrier, snack and confectionery applications |
| PET (heat sealable) | 12mic – 20mic | Mono or laminated | High-temperature sealing, excellent dimensional stability |
From lamination to finished roll — all under one roof
Flexographic print
Wide format, 8-colour flexographic printing in-house. UV, water-based and solvent-based inks. Short runs at high quality — no minimum colour commitment.
Rotogravure print
9-colour rotogravure with reverse print to register, 1,100mm wide at our Alrode facility. Ideal for high-volume, consistent colour reproduction.
Lamination
Solvent-free, water-based, solvent-based and UV lamination. Wide and narrow format. In-house capability at Germiston; solvent-based at Alrode.
High-speed slitting
In-house slitting from 40mm to 1,000mm on 3" and 6" cores. Precise width tolerances with full QC sign-off on every roll.
In-house testing
Burst strength testing, bond strength testing and in-depth Certificate of Conformity (COC) generation on every production batch.
