These PVDC heat shrink bags deliver high-barrier protection and are compatible with major automatic vacuum packaging machines, available in custom sizes, thicknesses, and print options to meet OEM requirements at scale.
Key Features of PVDC Heat Shrink Bags
High Oxygen & Moisture Barrier
Oxygen permeability ≤15cc/(m²·24h·0.1MPa) — effectively blocks oxygen, moisture, and aroma permeation for significantly extended shelf life.
Exceptional Puncture Resistance
Engineered for bone-in meat packaging and demanding transport conditions. Heat seal strength ≥16N ensures package integrity throughout the supply chain.
Superior Shrink Performance
Creates a tight, wrinkle-free package after heat shrinking. Conforms closely to irregular product shapes, minimizing purge and exudate leakage.
Low Temperature Durability
No brittleness or cracking under -40°C freezing conditions. Reliable performance for export cold chain and long-distance frozen logistics.
High Clarity & Gloss
Transparency ≥90%, haze ≤10% — superior product visibility enhances shelf appeal and retail display performance for fresh meat packaging.
Multi-layer Co-extrusion Technology
Advanced PVDC multilayer blown film process. Compatible with all major automatic vacuum packaging machines for efficient high-speed operations.

PVDC Heat Shrink Bags — Frequently Asked Questions
What are PVDC heat shrink bags and how do they work?
PVDC heat shrink bags are multilayer co-extruded packaging films that incorporate a polyvinylidene chloride (PVDC) layer as the oxygen barrier core. When heat is applied (typically 82–90°C hot water), the bag shrinks tightly around the food product, creating a vacuum-sealed protective barrier that blocks oxygen, moisture, and aroma transfer — significantly extending shelf life while preserving meat color and freshness.
What is the difference between HP2, HP3, and HP5 series?
HP2 is optimized for export cold chain and tuna — featuring maximum low-temperature durability (-40°C) and superior long-distance barrier performance. HP3 is designed for fresh and bone-in meats — prioritizing puncture resistance and retail-ready clarity. HP5 is tailored for cheese, dairy, ham, and smoked meats — delivering the tightest shrink conformity to minimize exudate leakage. All three share the same PVDC barrier core but differ in layer structure formulation to match specific application requirements.
Can I get custom sizes and printing on PVDC heat shrink bags?
Yes. Dale Packaging offers full OEM manufacturing with custom widths (180–400mm), thicknesses (50–60μm and beyond), bag types (curved or straight), and multi-color flexographic printing. Custom shrink rates and barrier specifications can also be formulated to meet specific application needs. Contact our sales team with your requirements for a tailored quotation.
What certifications do your high-barrier heat shrink bags have?
Our high-barrier heat shrink bags are manufactured in compliance with FDA 21 CFR for US markets, LFGB for EU/Germany, EU 10/2011 for European food contact materials, and produced under ISO 9001 quality management systems.
Are these bags compatible with automatic vacuum packaging machines?
Yes. All PVDC heat shrink bags from Dale Packaging are designed for compatibility with major automatic vacuum packaging machines including Multivac, Ulma, Reepack, and similar rotary and chamber vacuum systems. The bags feed reliably at high speeds and seal consistently for efficient production line integration.
What is the minimum order quantity (MOQ)?
MOQ varies by bag size, specification, and whether custom printing is required. Standard stock sizes have lower minimums. For OEM custom orders, minimum quantities are determined based on your specific requirements. Contact our sales team for a detailed quotation including MOQ, lead time, and shipping options.
What shelf life can I expect when using high-barrier heat shrink bags?
With oxygen permeability ≤15cc/(m²·24h·0.1MPa), these high-barrier heat shrink bags can extend fresh red meat shelf life to 30–60+ days under proper chilled conditions (0–4°C), and frozen product shelf life significantly longer. Actual results depend on product type, initial microbial load, processing hygiene, and cold chain integrity. We recommend conducting shelf life validation under your specific production conditions.
