Polyolefin Shrink Film Used in Notebook Packing
Books, magazines, manuals, and other paper products face two major challenges in POF shrink film packaging:
Heat Deformation Risk: Traditional high-temperature shrink films can cause book covers to curl and glued spines to soften or warp during packaging — particularly for thin volumes or heat-sensitive paper, where the risk of damage is even higher
Boxing Adhesion Issue: Immediately after shrinking, the film surface remains at an elevated temperature. If products need to be boxed right away, the
Core Product Positioning: Low-Temperature Heat-Slippery POF Shrink Film
STAM® S9 is a functional POF shrink film that combines low-temperature shrinkage with heat-slippery performance, specifically engineered for the packaging needs of books, magazines, and other paper products.
Two Core Technologies
1. Low-Temperature Shrinkage Performance
Achieves rapid shrinkage at lower temperatures, effectively preventing book curling and deformation caused by high heat
Low shrink force characteristic: automatically stops shrinking upon encountering resistance, preventing compression damage to the packaged item
Particularly suitable for packaging easily deformable items and heat-sensitive products
2. Heat-Slippery Performance
Film surface remains non-stick immediately after packaging, allowing instant boxing without adhesion between wrapped items
Enables smoother production line flow without the need for additional cooling wait time
Significantly improves post-packaging boxing efficiency

FAQS
What is POF shrink film?
POF, or Polyolefin Shrink Film, is a multi-layer, bi-axially oriented plastic film made from polypropylene and polyethylene polymers. It is renowned for its exceptional clarity, high strength, and superior sealing performance, making it an ideal packaging solution for a wide range of products.
What are the main advantages of POF over PVC shrink film?
POF is generally considered a superior alternative to PVC. Key advantages include: · Environmentally Friendly: POF is recyclable and produces significantly less smoke and odor when heated. · Higher Clarity & Gloss: Provides a brilliant, "window-like" display that enhances product appeal. · Softer and Safer: Less rigid than PVC, making it safer to handle and more resistant to cracking or tearing. · Stronger Seals: Offers more durable and reliable seals, reducing packaging failures.
Is POF shrink film eco-friendly?
Yes. Our POF film is 100% recyclable (often categorized as LLDPE-4) and contains no chlorides or plasticizers, making it a more sustainable choice compared to PVC. It also generates fewer emissions during the shrinking process.
What types of products is POF film best suited for?
POF is an incredibly versatile packaging material. It is perfect for: · Food items (bottles, canned goods, frozen foods, bakery products) · Consumer goods (books, toys, stationery) · Pharmaceutical and medical products · Promotional multi-packs and bundling · Electronics and hardware items
What type of machinery is required to use POF shrink film?
POF is compatible with most L-bar sealers, sleeve wrappers, automatic shrink wrapping systems, and manual heat guns. The key requirement is a heat tunnel or heat source capable of reaching the appropriate shrinking temperature, typically between 160°C - 200°C (320°F - 390°F).
How does POF create such a tight and secure pack?
POF film is bi-axially oriented during manufacturing. When heat is applied, the film's "memory" causes it to contract tightly and uniformly in all directions around the product, conforming to its shape and creating a tamper-resistant, secure bundle.
How does the cost of POF compare to other films?
While the per-roll cost of POF may be higher than some alternatives, it often provides a better total value. Its superior strength can allow for the use of a thinner gauge film, reducing material usage. Furthermore, its reliability reduces waste from seal failures and repackaging, improving overall operational efficiency.
Is POF film resistant to cold temperatures?
Yes. One of the significant benefits of POF shrink film is its excellent performance in cold environments. It remains flexible and resistant to brittleness and cracking, even in freezer applications.
Can POF film be printed on?
Absolutely. POF film accepts high-quality flexographic and rotogravure printing exceptionally well. Its inherent clarity and gloss provide a vibrant, high-resolution background for logos, branding, and product information.
How can I choose the right gauge (thickness) for my product?
The right gauge depends on your product's weight, shape, and packaging machinery. · 45 Gauge(12mic): Ideal for light-weight products and simple bundling. · 60 & 75 Gauge(15mic&19mic): Our most popular, all-purpose gauges for a wide range of consumer products. · 100 Gauge & heavier(25mic above): Designed for heavy, bulky, or sharp-edged items requiring maximum durability. Our technical team can help you select the perfect gauge for your specific application.
