2 rolls-16" centerfold polyolefin shrink film (60 gauge) delivers consistent heat shrink performance for multi-pack and retail packaging applications. This gauge and width are designed for high-speed automatic packaging lines while maintaining tight film control and tamper-evident seals.
Manufacturers value this format for its clarity, puncture resistance, and low-temperature shrink characteristics. The centerfold layflat structure supports easy automated loading and minimizes roll breaks during changeovers.

Processing Parameters for Reliable Shrink
Recommended Temperature and Speed Ranges
Optimal shrink results depend on tunnel or heat gun settings that match the 60 gauge polyolefin profile. Consistent conveyor speed and temperature zones reduce film distortion and sealing failures.
Conveyor Speed and Rest Time Guidelines
Slower initial conveyor speeds improve film drape over irregular packages, while adequate rest time in the cooling section prevent shape recovery and wrinkles.
Film Handling and Storage Practices
Core Size, Roll Diameter, and Storage Conditions
Proper storage in a clean, dry environment minimizes moisture uptake and keeps the centerfold layflat structure intact for smoother automated feeding.
Core Specifications and Compatibility with Equipment
Confirm core dimensions and arbor requirements on your shrink wrappers to avoid roll slippage, misalignment, and excessive changeover downtime.
Performance and Quality Attributes
Clarity, Seal Strength, and Shrink Uniformity
High-clarity polyolefin film provides premium display appeal, while uniform shrinkage around corners and edges supports tamper-evident seals without weak points.
Puncture and Tear Resistance in Multi-Pack Applications
The 60 gauge centerfold build offers sufficient resistance to handle automated handling, stacking, and palletizing while preserving package integrity.
Operational Guidelines and Recommendations
- Confirm wrapper compatibility with 16-inch width and 60 gauge thickness before production runs.
- Set tunnel temperatures gradually within the recommended range and monitor seal integrity across package types.
- Control conveyor speed to allow uniform film drape and sufficient cooling before discharge.
- Inspect rolls for edge damage and core misalignment upon receipt and prior to changeover.
- Maintain stable humidity and clean storage conditions to reduce film static and handling issues.
FAQ
Reader questions
Will this 2-roll 16" centerfold fit my current shrink wrapper?
Verify your machine’s core diameter, roll width capacity, and film path clearance; most standard wrappers designed for 16-inch wide centerfold film will accommodate this format.
What tunnel temperature range works best for 60 gauge polyolefin shrink film?
Typical recommended tunnel temperatures fall between 275°F and 325°F (135°C to 163°C), adjusted for package size, speed, and desired seal strength without causing film burn or excessive shrinkage.
Can this film be used for both manual hand tools and automatic high-speed lines?
Yes, its centerfold layflat structure and consistent gauge perform well on semi-automatic sealers as well as high-speed inline shrink tunnels, provided feeding and cooling parameters are tuned accordingly.
How should I store unused rolls to minimize edge waves and core misalignment?
Store rolls upright in a controlled environment with moderate temperature and humidity, using appropriate racking to prevent rim damage and maintain the integrity of the centerfold layflat profile.
