Shrink wrap film is a versatile and essential packaging solution for businesses and individuals alike. It's used to protect and preserve products during shipping, storage, and display.

There are several types of shrink wrap film, including polyolefin, polyvinyl chloride (PVC), and polyethylene. Each type has its own unique characteristics and applications.

Shrink wrap film is available in various widths and lengths to suit different packaging needs. It's also available in different gauges, or thicknesses, to provide the right level of protection for your products.

Whether you're packaging small items like electronics or large items like furniture, shrink wrap film is a reliable and efficient solution.

Types of Packaging Film

Pre-perforated film is designed to offer excellent air escapement and fast, dependable shrinkage without the "dog-ears" effect, making it a convenient option for packaging and bundling.

PVC Shrink Film is a great alternative to polyolefin film, shrinking at lower temperatures to speed up production.

There are two main types of shrink film commonly used for packaging and bundling applications: PVC film and Polyolefin (POF) film.

Choosing the Right Film

Choosing the right film for your packaging needs is crucial to ensure a secure and attractive presentation.

Consider the type of product you're wrapping, as some films are designed specifically for fragile items or those with sharp edges.

For example, a film with a high cling strength is ideal for wrapping irregularly shaped items, such as boxes or bottles.

Shrink film is a versatile material, and understanding its terminology can help you make informed decisions. Common terms include Centerfold Shrink Film, which is folded in half lengthways for easier and quicker wrapping.

Dog Ears are a common feature in packages wrapped with PVC shrink wrap, characterized by triangular projections of unshrunk film at the corners.

Impulse Sealers use a heating element that pulses with voltage during the sealing process. This heat mends polymer materials together, creating a strong seal.

L-Bar Sealers have a sealing surface in the shape of a backward "L" and are a universal sealer for those who want to seal faster than with an impulse sealer.

Machine Direction refers to the direction the film is manufactured and moves through the sealing equipment.

PVC shrink film is a universal shrink wrap made from Polyvinyl Chloride, the third most-produced plastic in the world.

For Centerfold

Centerfold shrink film is a convenient and efficient way to wrap objects. It's folded in half lengthways, making wrapping easier and quicker.

To determine the width of shrink wrap tubing needed, start by measuring the circumference of the object. Add 10% to the circumference, then divide the final number by two.

The type of shrink film used can affect the shrink rate. For example, PVC 75 Ga shrink film has a fair shrink rate at 180 and 200 F°, but a good rate at 225 F°.

Here's a comparison of shrink rates for different types of centerfold shrink film:

PVC shrink wrap tubing can shrink up to 40%, so it's a good idea to choose a size that's slightly larger than needed.

Application and Tools

Heat guns are a necessity when using shrink film to bundle your packages.

Heat allows the plastic film to shrink and tighten over the package, creating a strong waterproof seal around the product or products being bundled. This seal is essential for protecting your items from moisture and damage.

A multi-purpose heat gun is ideal for shrink film uses, providing consistent heat for efficient sealing.

Guide to Heat Film

Heat film is a type of thermal insulation material that can be applied to various surfaces for temperature control. It's available in different types, including reflective, radiant barrier, and foam-backed films.

A reflective heat film can reduce heat gain in buildings by reflecting solar radiation, with some types able to reflect up to 97% of the sun's rays. This can lead to significant energy savings.

Heat film can be applied to various surfaces, including metal roofs, walls, and floors, as well as windows and skylights. It's an ideal solution for areas with high temperatures or direct sunlight exposure.

In some cases, heat film can be applied directly to the surface, while in others, it may require a primer or adhesive for optimal performance. This depends on the type of surface and film being used.

Heat film can be cut to size using scissors or a utility knife, making it easy to apply to specific areas or shapes. It's also available in rolls for larger applications.

Heat film is a relatively inexpensive solution for temperature control, with costs ranging from $0.50 to $5.00 per square foot, depending on the type and quality.

Common Problems

Wrinkles can be a major problem when shrink wrapping, especially for companies new to the process. Lines in the shrink film after heat is applied can be fixed by applying more heat to the film.

Applying more heat to wrinkled areas can resolve the issue, and if using a heat tunnel, slowing down the belt speed or increasing the temperature can also help.

Dog ears are another common issue, where shrink film bunched up in the corners of the package. Excessive dog ears can be prevented by applying more heat to the shrink film.

Burn holes occur when too much heat is applied to the shrink film. If using a heat gun, backing it further away from the product can prevent burn holes.

Shrink film tears are often caused by the type of film being used or its thickness. If experiencing tears, a thicker film or a different kind of film should be considered.

Evaluating Film Performance

When evaluating the performance of shrink wrap film, clarity of vision is key. This is because shrink wrap film is used to wrap products for display and shipping, and a clear view of the product is essential for customer appeal.

Shrink wrap film can be made of various materials, including polyvinyl chloride (PVC) and polyethylene (PE). PVC is more durable and resistant to scratches, but PE is more flexible and easier to apply.

Shrink wrap film can be applied using heat guns or shrink wrap machines, which help to evenly distribute heat and achieve a smooth finish. This is especially important for products with irregular shapes or textures.

A smooth finish is not only visually appealing but also helps to prevent moisture from getting trapped between the film and the product, which can lead to mold or mildew growth. This is particularly important for products that are sensitive to moisture, such as food or electronics.

The thickness of the shrink wrap film also plays a crucial role in its performance. Thicker films provide better protection against scratches and damage, but may not shrink as evenly as thinner films.

In some cases, the color of the shrink wrap film can also be a consideration, particularly if the product is to be displayed in a specific environment or with specific branding requirements.

Frequently Asked Questions

Can you shrink wrap at home?

Yes, you can shrink wrap at home using a heat gun and shrink wrap bags, making it a convenient and cost-effective way to package gifts and products. Follow the manufacturer's instructions for the best results.

Can you use cling film as a shrink wrap?

Cling film is not suitable for shrink wrapping as it doesn't have the necessary properties to shrink down and seal around the item. For effective shrink wrapping, use a specialized plastic film designed for this purpose.
