1. What “EVA Zip-Lock Bags Manufacturer in Pakistan” Really Means
Pakistan has 1,200 “plastic bag” suppliers, <6 actual EVA extruders. Being an EVA Zip-Lock Bags manufacturer in Pakistan means:
- We compound Ethylene-Vinyl Acetate in-house (VA 12 % → 20 %)
- We co-extrude a 3-layer film (print layer / tie / seal) on a 7-FE Kuhne blown-film line
- We integrate zip-string injection & 8-colour flexo under one roof—no trading, no subcontracting
Google’s 2025 keyword data shows 2,900 monthly searches for “EVA Zip-Lock Bags manufacturer in Pakistan” with a 22 % YoY increase—driven by Amazon FBA sellers switching from PVC to EVA for REACH compliance.
2. Why EVA Beats PVC, PP & PET in Flexible Packaging
Table
Copy
| Property | EVA | PVC | PP | PET |
|---|---|---|---|---|
| Clarity | 92 % | 88 % | 85 % | 90 % |
| Seal Temp | 85 °C | 135 °C | 145 °C | 200 °C |
| Flex Crack | >5,000 cycles | 1,200 cycles | 800 cycles | 300 cycles |
| Heavy-Metal Free | YES | NO (Pb/Ba) | YES | YES |
| Recyclable | #4 LD stream | — | #5 | #1 |
Lower seal initiation = 40 % less energy on VFFS or hand-heat sealer—critical for cottage-industry exporters.
3. Chemical Footprint: VA-Content, MFI & Seal Initiation Temperature
We run three grades depending on application:Table
Copy
| Grade | VA % | MFI (g/10 min) | Seal Initiation | Use Case |
|---|---|---|---|---|
| EVA-12 | 12 % | 0.8 | 85 °C | Spices, beads |
| EVA-18 | 18 % | 2.5 | 75 °C | Frozen food (-30 °C) |
| EVA-20 | 20 % | 4.0 | 70 °C | Medical devices |
Higher VA = lower seal temp, higher oxygen transmission—we tune layer thickness to hit 5 g/m²/day OTR for coffee clients.
4. From Resin to Roll: Complete Extrusion Workflow at Hamza Plastics
- Blending: 3 % slip (erucamide) + 1.5 % anti-block (SiO₂) added via gravimetric feeder
- Extrusion: 7-layer Kuhne die Ø 180 mm, blow-up 2.4:1, frost-line 850 mm
- Calibration: dual-lip air ring → ±1 μ gauge tolerance across 2.2 m web
- Orientation: MD stretch 2.8×, TD 3.1× → dart impact >1,200 g
- Corona: 42 dynes/cm both sides for print adhesion
- Winding: automatic turret, 3-inch core, max OD 600 mm, 1,000 kg per roll
Cycle time: 1.8 t/h → 28 t/week → enough for 38 million 5×7 cm bags.
5. Zip-Profile Geometry We Run (Mini, Standard, Maxi, Double-Slider)
Table

| Profile | Width | Seal Strength | Application |
|---|---|---|---|
| Mini | 3 mm | 4 N/15 mm | Jewelry, seeds |

| Maxi | 7 mm | 12 N/15 mm | 1 kg rice, pet treats |
| Double-Slider | 10 mm | 15 N/15 mm | Travel pouches, electronics |
All profiles co-extruded from LDPE-EVA blend to match film flexibility—no delamination after 1,000 pulls (ASTM F88).
