Packtastic PVDC High‑Barrier Shrink Bags are premium multi‑layer co‑extruded packaging solutions engineered to protect a wide range of perishable foods – including meat, poultry, tuna, and cheese. The key barrier layer is PVDC (Polyvinylidene Chloride) , which provides outstanding oxygen and moisture resistance that remains stable even in high‑humidity cold‑chain conditions – outperforming EVOH for fresh meat and seafood applications. When heat‑shrunk (85–90°C), the bag forms a wrinkle‑free “second skin” that conforms tightly to the product, eliminating air pockets, reducing purge loss, and preserving natural colour, flavour and texture.
With proven shelf‑life extension – fresh red meat lasts 7–9 days (vs. 3–5 days), pasteurised meat up to 90 days, chilled tuna up to 4 months, and cheese up to 12 months depending on variety – these bags are ideal for processors, packers and retailers who demand premium product presentation and export‑ready durability. Available in custom sizes, thicknesses, multi‑colour printing (up to 20 colours), and various styles (curved, straight, taped, perforated), with low MOQs and full food‑grade certifications (FDA, BRC, HACCP, ISO, Kosher).
These are tubular co‑extruded films used for vacuum packaging of food products. After the product is inserted and vacuum‑sealed, the bag is passed through a hot‑water tunnel (85–90°C), causing the film to shrink tightly around the contents. The result is a skin‑tight, glossy, transparent package that maximises shelf life and visual appeal. PVDC is chosen for its exceptional barrier against oxygen, moisture and aromas – and its performance does not deteriorate in wet environments, making it the preferred choice for fresh red meat, poultry, seafood and cheese.
Superior barrier – PVDC offers OTR ≤5 cc/m²·24h, stable at high RH; protects against oxidation, dehydration and off‑flavours.
Extended shelf life – Tailored to each product:
Fresh beef/pork/lamb: 7–9 days (refrigerated)
Pasteurised meat: up to 90 days (0–4°C)
Chilled tuna: up to 4 months
Hard cheese: up to 12 months
Skin‑tight shrink – Shrinkage >50% at 85–90°C; no wrinkles, minimal purge, excellent shape retention.
High clarity & gloss – Crystal transparency highlights product colour and freshness, boosting retail appeal.
Puncture resistant – Tough enough for bone‑in cuts and handling damage.
Low‑temperature shrink option – 85°C available to preserve colour and delicate textures.
Anti‑fog coating (optional) – Prevents condensation for clear visibility.
Food‑grade certified – FDA, BRC, HACCP, ISO 9001, Kosher compliant.
Full customisation – Sizes (width up to 500mm+), thickness (45–300µm), printing (20 colours), bag styles (curved/flat/taped/perforated).
