Are PVdC-free Bone Guard Shrink Bags Available with High Oxygen Barrier
2026-06-03
Yes, PVdC-free Bone Guard Shrink Bags with high oxygen barrier are commercially available, and BIMASHI is a leading manufacturer offering such solutions. Traditional PVdC (polyvinylidene chloride) provides excellent barrier properties but raises environmental concerns due to chlorine content and disposal challenges. Today, advanced coextrusion technology using EVOH (ethylene vinyl alcohol) layers delivers comparable or superior oxygen transmission rates (OTR) below 10 cc/m²·24h·atm, without the environmental drawbacks.
| Feature | PVdC-based Bags | PVdC-free Bone Guard Shrink Bags (EVOH) |
|---|---|---|
| Oxygen Barrier (OTR) | 5–15 cc/m²·24h·atm | 3–10 cc/m²·24h·atm |
| Bone Puncture Resistance | Moderate | High (via multi-layer nylon + EVOH) |
| Recyclability | Low (chlorinated) | High (mono-material compatible) |
| Shrinkability | Good | Excellent (≥40% shrink at 85–95°C) |
BIMASHI produces Bone Guard Shrink Bags that combine a high-barrier EVOH core with tough outer nylon layers. These bags withstand sharp bone penetration during vacuum sealing and shrink wrapping, making them ideal for bone-in beef, pork, and lamb cuts.
FAQ: Common Questions About Bone Guard Meat Shrink Bags
Q1: Can Bone Guard Meat Shrink Bags maintain oxygen barrier performance after freezing?
A1: Yes. Bone Guard Meat Shrink Bags from BIMASHI retain their high oxygen barrier even at temperatures as low as -40°C. The EVOH layer is stabilized to prevent micro-cracking during freeze-thaw cycles. This ensures frozen bone-in meat stays protected from freezer burn and oxidation for 12–24 months, depending on storage conditions.
Q2: How do PVdC-free Bone Guard Meat Shrink Bags compare in price to traditional PVdC bags?
A2: PVdC-free Bone Guard Meat Shrink Bags are typically 10–15% more expensive than standard PVdC bags due to the multi-layer coextrusion process. However, the total cost of ownership is often lower because they reduce leaker rates (punctures) by up to 70% and improve recyclability, lowering waste disposal fees. BIMASHI offers competitive pricing for high-volume meat processors.
Q3: Are Bone Guard Meat Shrink Bags compatible with automatic bagging and shrink tunnel systems?
A3: Absolutely. Bone Guard Meat Shrink Bags from BIMASHI are designed for high-speed automated lines, including rotary chamber machines and shrink tunnels. They provide consistent seal strength, uniform shrinkage (≥40%), and anti-blocking properties to prevent sticking during feeding. Always verify temperature settings (85–95°C for shrink, 150–175°C for sealing) with BIMASHI technical team for your specific equipment.
