How to choose high-quality stretch film?

Choosing high-quality stretch film is crucial for ensuring the safety of goods during transportation and storage. Here are some key factors to consider when choosing high-quality stretch film:

Material quality: High quality stretch film is usually made of linear low-density polyethylene (LLDPE), which has good tensile properties, tear resistance, and puncture resistance. Check whether the product uses high-purity raw materials to ensure its durability and reliability.

Stretching rate: The stretching rate of a stretch film refers to the degree to which it can be stretched. A higher stretch rate means that more goods can be wrapped with less film, thereby saving costs. However, attention should also be paid to the retention and recovery of the membrane under high tensile conditions.

Transparency: The high transparency stretch film makes it easier for you to view the items inside the package, which is crucial for inventory management and safety checks.

Adhesive and sealing properties: High quality stretch film should have appropriate self-adhesive properties to securely wrap around goods without the use of additional tape. Meanwhile, it should also be able to maintain good adhesion performance under various temperature conditions.

Thickness: Choose the appropriate thickness according to the type of goods that need to be packaged. Thicker films are more suitable for heavy or sharp edged items, while thinner films are suitable for light or smooth surface items. Generally speaking, the thickness ranges from 8 microns to 30 microns.

Environmental adaptability: Consider the performance of stretch film under different environmental conditions, such as temperature changes, humidity, etc. Some high-end products can maintain excellent performance even under extreme weather conditions.

Brand reputation and service: Choosing stretch films from well-known brands can ensure product quality, and these brands often provide better after-sales service and technical support.

Environmental considerations: If possible, choose products that are recyclable or made from recycled materials, which can help reduce the impact on the environment.

By considering the above factors comprehensively, you can better choose high-quality stretch film that suits your needs. In addition, obtaining samples for actual testing is also a good method for evaluating the performance of stretch films.

What Is Stretch Wrap Gauge ?

Gauge is a measure of a stretch wrap’s thickness. Generally, the higher the gauge, the higher its resistance to breakage. General purpose 80-gauge wrap is the industry standard, and can secure loads up to 2,400 lbs.

Higher gauge wraps tend to be more expensive, but are thicker and do not need to be wrapped around as many times on a job.

Gauge can be converted into mils, microns or other units. Here is a conversion chart:

Popular Stretch Wrap Gauges

37 Gauge: A pre-stretch wrap suitable for light, uniform loads of up to 800 lbs

60 Gauge: A light true-gauged film suitable for light to medium loads up to 1,600 pounds.

80 Gauge: A versatile, medium-duty true-gauged film for loads up to 2,400 pounds. This is the most common stretch film thickness.

100 Gauge: A heavier-duty true-gauged film that can hold loads up to 3,000 pounds. Machine stretch wrap in this gauge can be used to wrap pallets of heavy, irregular objects such as steel beams or 55-gallon drums.

150 Gauge: A heavy-duty true-gauged stretch film for extremely heavy loads, loads with many sharp points or corners, and heavy irregular objects that may shift during transit. Typically must be machine-applied to achieve proper tension.

Types of Stretch Wrap

• Pre-Stretched Stretch Wrap has been mechanically stretched prior to rolling, so it is thinner than its true-gauged equivalent. Pre-stretching 80-gauge film results in a 37-gauge pre-stretch film. This creates a lighter wrap, but with a similar hold to its true-gauge counterpart.
• True-Gauge Stretch Wrap has not been pre-stretched. The thickness it has afte the extrusion process is the thickness it has on the roll.
• Hand Films are great for small shipping and containment applications, and can be used to bundle items, or hold items in place on a pallet. A single operator can wrap a pallet with hand film in just a few minutes by stretching the film while walking around the pallet. Hand wrapping is typically ideal for those who unitize less than 10 pallets per day, have decentralized warehousing or need a backup to powered stretch wrapping equipment.

• Opaque/Product Concealing Wraps are completely solid in color, not clear or tinted. These wraps provide privacy, conceal shipments, and help to prevent theft.
• Corrosion Inhibiting Wraps protect shipments that are prone to corrode from moisture.
• Anti-Static Wraps protect shipments that contain sensitive electronics from static discharge.
• Machine Film is used with powered stretch wrapping equipment. There are several different types of powered stretch wrapping equipment available today. The most common are rotary spiral pre-stretch machines. The Rotary Spiral Pre-Stretch machine wraps the pallet load in a spiral fashion using film widths of 20” or 30”.
• Colored/Tinted Stretch Film is used to organize and identify pallets and products.

Things to Consider When Choosing Your Stretch Wrap

• The weight of the load. The heavier the load, the stronger your stretch wrap gauge will need to be.
• The shape of the load. Uniform loads, such as pallets of same-size boxes, require less holding power and durability (and a lower gauge) than highly irregular or unstable loads with lots of sharp corners and edges.

• Do you and your staff have the proper tools and training? Large, heavy, and oddly shaped items that require high-gauge stretch wrap may require the use of stretch-wrapping machines in order to be wrapped safely and efficiently. These machines unfortunately are not typically cheap, and you want to make sure that any staff using such machines is properly trained in order to maximize the machine's benefits and prevent any workplace incidents. (For wrapping of any kind, proper training is also highly recommended to save money long-term; if an employee is over-using stretch wrap on each load, or using a thicker and more expensive wrap than is needed, over time these costs will add up!)
• Do my products have special needs? Some products need added protection from one thing or another, and this needs to be put into consideration when wrapping. For example, certain electronics might benefit from anti-static wraps, and more expensive products may benefit from opaque wraps to better conceal their value. Consider everything before finalizing your stretch wrap purchase.
• Do I need a stretch wrapping machine? You will need to evaluate your shipping volume, staff size, and product types in order to answer this question. There are all types of machinery you can purchase to help apply your stretch wrap thoroughly and efficiently. Certain large, bulky, and oddly shaped products will highly benefit from the uniform tension of machine-applied stretch wrapping.
