Factors to Consider in Choosing the Best Shrink Wrapping System

Read more

Choosing the right shrink wrap equipment is crucial for the success of your packaging process. With a variety of shrink wrapping systems available to suit different products and budgets, it’s vital to consider several key factors before making a decision:

1. Material
When selecting a shrink wrapper, consider the films to avoid potential issues that may lead to waste. Understanding the type of products being wrapped is essential, as different film components provide various levels of protection. Fragile items typically require a heavy-duty film. (Further details on film types can be found below.)

2. Speed
The speed of the machine is important based on your production goals. Fully-automated machines yield results quickly, while manual wrappers take more time. If quick turnarounds are necessary, an automated solution may be the best fit for your business.

3. System Compatibility
Ensure your shrink wrap machine can integrate with any existing packaging operations and accessories, like conveyors, to avoid compatibility problems during upgrades.

4. Size
Shrink wrap machines come in different sizes, so choose one that fits the items you plan to wrap.

5. Workspace Considerations
Larger machines often require more space. Ensure you have the proper area to accommodate the machine’s dimensions.

Types of Films Used in Shrink Wrapping

Polyolefin Shrink Film
 
Polyolefin films are popular for several reasons: they emit fewer odors when sealed, provide a stronger hold, and have flexible storage options. They’re chlorine-free, therefore, no harmful gas is produced. Additionally, polyolefin can withstand a range of temperatures without losing integrity.

Uses
This type of shrink film is versatile, suitable for various products, including toys, sporting goods, food, stationery, and more.

Drawbacks
The main disadvantages of polyolefin films are their cost and machine compatibility, as they are often pricier than PVC films and may not work with all machines.

Cross-Linked Polyolefin Shrink Film

Cross-linked films are sterile and FDA approved for food contact, offering excellent clarity for displaying products. They produce minimal residue, extending the life of sealing devices and are optimized for high-speed operations.

Uses
Similar to polyolefin films but suitable for high output applications and heavier products.

Drawbacks
Cross-linked films require higher temperature seals, which can harm heat-sensitive items, and this results in higher energy costs.

PVC Shrink Film

PVC, or Polyvinyl Chloride, is widely used but has environmental drawbacks. It was once the preferred material but has been largely replaced by polyolefin.

Uses
Suitable for packaging non-edible products like boxes and media packaging.

Drawbacks
Sealing strength issues and environmental concerns are significant drawbacks. PVC can harden in cold and soften in heat, negatively affecting its flexibility.

Shrink wrap offers moisture resistance and protects items from dirt, dust, and scratches, ensuring a sturdy protective layer around your products.

The global shrink wrapping market is expanding, with expected growth of around $415 million, making it a vital consideration for your business.

If you're interested in enhancing your packaging operations, investing in a shrink wrap machine could give you the competitive edge you need.

When selecting a shrink wrap machine, consider the following:

• PVC is ideal for everyday products.
• POF is suitable for FDA-approved applications involving consumables.

Select the right mil thickness; higher numbers indicate stronger films.

Finding the Right Shrink Wrap Machine

When seeking shrink wrap systems, it's essential to classify them based on your requirements. Different machine sizes cater to varying product types and uses.

Consider your product volume. Smaller machines are ideal for lower outputs, while larger, automated systems serve high-volume production lines. The cost of low-volume machines typically ranges from $200 to $500, while higher-end models can serve needs of eCommerce businesses more efficiently.

Heavy-duty machines for industrial use may range from $30,000 to $40,000, capable of packaging over 100 items per hour.

Current shrink wrap machines mainly include the I-Bar and L-Bar sealers, apart from custom models used in extensive assembly lines.

The I-Bar Shrink Wrapper

This manual device uses an I-bar sealer and a feed roller for centerfold films. It's perfect for small-volume manufacturers, allowing for custom bag sealing. An I-bar can seal approximately 200 items daily, making it suitable for smaller products.

The L-Bar Shrink Wrapper

Utilizing an L-shaped impulse sealer, the L-Bar machine seals two intersecting sides of packaging, ideal for heavy-duty applications with quick seal times and high-volume output.

Recommended I-Bar models include:
AIE-I - I Bar Shrink Wrap System 13 inch
AIE-I - I Bar Shrink Wrap System 18 inch
AIE-I - I Bar Shrink Wrap System 24 inch
AIE-I - I Bar Shrink Wrap System 32 inch
AIE-I - I Bar Shrink Wrap System 40 inch

Support Units: Shrink Wrap Tunnels

For automated options, consider shrink wrap tunnels, which offer a temperature-controlled environment for speedy packaging, moving products smoothly through the process.

Industrial Shrink Wrap Machines

For large-scale operations, industrial machines can be directly linked to automation systems, providing high-capacity packaging without the need for operator intervention.

Find The Right Shrink Wrap Machines

Depending on your operation size, semi-automatic devices like I-bar or L-bar sealers, combined with shrink-wrap tunnels, can meet your needs.

If you seek professional packaging solutions, look no further than Pack Secure, which supplies a wide range of options including POF shrink films, shrink machines, and sealers.
