Shrink Wrap Packaging Experts - We Do It Right!

FDA Approved Shrink Packaging Solution for Cake/Pizza Cartons

Overview:

A large manufacturer of cake cartons, pie cartons & pizza boxes in Toronto wanted to upgrade their existing process, and incorporate a faster and effective way to wrap cake and pizza boxes. They were wrapping on a sleeve wrapper which left open holes on each side of the package. Their customers needed a fully enclosed package to comply with food packaging guideline’s under CFIA (Canadian Food Inspection Agency) & FDA food & safety regulations.

An Impak technical application expert worked with this company to get a better understanding of their expectations and recommended a highly efficient Automatic Side Sealer for Cake Cartons, Pie Boxes & Pizza Boxes. Since the implementation of the new shrink wrapping system, the customer has reduced its packaging cost by 15% and can run different sized boxes at the required speeds without having to change the film.

Stretch wrapping basics

Stretch wrapping is a technique used throughout the packaging industry to secure products to a skid and provide extra protection while in transport. This technique is particularly useful while shipping several boxes or products on a skid. Pallet Wrapping will ensure that your products are safe, stabilized and secure so they reach your customer without being damaged or tampered. This article aims to give you a clear understanding of how stretch wrapping works and how it is implemented. You need to follow certain steps so that you stretch wrap your products properly preventing them from getting damaged during the shipping process.

stretch film

Stretch Film is a highly stretchable plastic film that is used in the stretch wrapping process. This highly stretchable film is wrapped around the boxes while adjusting the tension, wrapping the skid providing a secondary protection. There are two types of stretch film which are commonly used: Machine stretch film and Hand stretch film.

Stretch Wrapping Equipment

Fox FPS 300 Pallet Wrapper with wrapped palletPallet Wrappers/Stretch Wrappers tightly wrap a loaded skid or a pallet with machine stretch film. A loaded pallet is placed on the turn-table and with the carriage mounted with stretch film, the turntable rotates dispensing film and wrapping the pallet. Pallet Wrappers tightly wrap the pallet making it stable, air-tight and clean. You can also use a hand wrapper to wrap the pallet by hand using hand stretch film.

Different types of pallet wrappers

The Turntable Pallet Wrapper is like a spinning plate for pallets. Just like the name sounds, this machine has a turntable on the bottom of the structure that spins. You place the pallet on the rotating platform, and a roll of stretch film is dispended high to low as it turns. You can adjust the tightness and number of wraps as needed. It’s an easy and effective way to protect and contain products during transport. 

Imagine a big oscillating arm that hugs your pallet with stretch film to ensure containment during transport – that’s the Rotary Arm Pallet Wrapper. The pallet stays still, and the arm moves around the skid, wrapping the film from top to bottom. This method is great for fast and stable wrapping, especially for tricky loads that may wobble.

The Orbital Pallet Wrapper is perfect for irregularly shaped loads. Instead of spinning the pallet, it wraps the film around the load horizontally from all sides. This ensures that every part of the load is securely covered, preventing any shifting during shipping. This type of stretch wrapping machine is perfect for long product like furniture and cabinetry.

The Mobile Pallet Wrapper is like a compact wrapping machine on wheels. You can take it anywhere in your warehouse, no fixed spot needed. Just place the pallet on the floor, attach the film, and let the machine move around the pallet to wrap it up neatly. It’s convenient, safe and saves time!

Key Considerations FOR hand WRAPPING

The following are the steps to be considered before stretch wrapping a skid using a hand film:

1. Select the right size pallet or skid

Make sure you stack your boxes or products using the right size skid.  Using a skid that is too large or too small will result in an insecure and unstable load. The best size is one that is not larger than the products placed on top otherwise the plastic may tear on the sharp pallet corners; yet the pallet has to completely cover the base area of the products you want wrapped or you may have damage to your products in shipping.

2. Stack the base of the skid properly

If you have different size boxes, make sure to place the larger heavier boxes on the pallet first. Make sure not to leave any gaps and occupy as much space as you can to make the base stable and secure.

3. Stack the rest of your boxes on the skid

Properly place the remaining boxes or products on the skid. Make sure that your boxes do not cross the edges of the pallet and placed them as close as possible to each other in order to prevent them from moving after being wrapped. Do not stack your pallet too high as it can destabilize the load by raising the center of gravity. Make sure your skid is in cubical or square shape.

4. Start the Stretch Wrapping Process

Tie the stretch film around the corner of the skid. This will ensure that the film does not come off while wrapping. While holding the hand stretch wrapper, start walking around the skid. Once you reach the corners of the skid, tightly secure and apply tension ensuring it is nice and tight around the load. Always start from the bottom and then go towards the top.  It is recommended that you go around the skid at least 5-6 times to ensure stability. Once the wrapping is finished, check the skid thoroughly for sturdiness. If the load is moving and is not stable, you should consider wrapping it again. Once your pallet is stable and sturdy, tear the stretch wrap from the skid and you are done.

5 Things You Need to Know about Downgauging Stretch Wrap

In recent years, the growing concern for environmental sustainability has led to significant changes in the packaging industry. One such development is the adoption of downgauging stretch film, a process that involves reducing the thickness of the film while maintaining its performance characteristics. In this article, we will explore the concept of film downgauging, its advantages, and address common concerns about the quality and appearance of the packaging.

Sustainable Stretch Film Icon

1. What is film downgauging?

Film downgauging refers to the process of reducing the thickness of stretch films used in packaging without compromising their performance. Traditionally, plastic films were thicker to ensure strength, durability, and barrier properties. However, advancements in technology and material science have allowed manufacturers to create thinner films that meet the same quality standards as their thicker counterparts.

2. Why should you consider downgauging Stretch film

Downgauging stretch film offers several benefits, both for businesses and the environment. By reducing the amount of material used in packaging, companies can significantly decrease their carbon footprint and overall waste generation. Thinner films require fewer raw materials during production, resulting in lower energy consumption and greenhouse gas emissions. Moreover, downgauging can lead to cost savings, as less material is required for packaging without compromising on performance.

3. Will it still meet quality requirements?

One of the most common concerns about downgauging stretch film is whether it will meet the necessary quality requirements. However, manufacturers have made significant strides in developing thin films that maintain the necessary toughness, barrier properties, shelf-life, and resistance to damage during transportation and end use. Advanced materials and technologies allow for the creation of thinner films that possess the required strength and durability, ensuring the packaged products remain intact and protected. 

4. Does the package still maintain its shelf appearance?

Maintaining the visual appeal of packaged products is essential to brand identity and consumer perception. Fortunately, downgauging plastic film does not necessarily compromise the package’s shelf appearance. With advancements in printing and coating technologies, it is possible to enhance the visual aesthetics of thinner films, ensuring that they still look as good as their thicker counterparts on store shelves. Packaging designers can employ various techniques to maintain branding elements and eye-catching designs, ensuring consumer satisfaction.

5. Will consumers notice?

Consumers are increasingly conscious of sustainability issues, and many actively seek out products with environmentally friendly packaging. According to The Dow Chemical Co. study conducted in 2011, consumers may notice a change in packaging thickness if given more than a 10% reduction. However, the quality and functionality of the package, as well as the brand’s commitment to sustainability, are often more important factors for consumers. By effectively communicating the sustainability of downgauging, companies can enhance their brand reputation and appeal to environmentally conscious customers.

In general, the process of downgauging stretch film for packaging offers a range of benefits, such as reducing the environmental impact and saving costs. As you read through this article, you may consider the option of downgauging your stretch film. By planning how downgauged packages feel to customers and promoting sustainability, it is possible to provide a solution that satisfies brand owners, retailers, and consumers.

Whether you decide to pursue downgauging or explore newer and more innovative stretch films, it is advisable to involve a packaging expert who can assess your packaging operation and help determine the most suitable film for your specific application. You can trust our team of highly experienced packaging specialists who possess a deep understanding of stretch film wrapping and can provide valuable guidance.

Best shrink wrap machine for food

When it comes to packaging food items, choosing the right method is crucial to ensure freshness, protection, and aesthetics. Among the various packaging machines available, a shrink wrap machine stands out as a popular choice, particularly for hard fresh produce like cucumbers and cabbages, frozen food that can be scattered like pizza, and any food items with trays. The reason is that shrink wrapping food items offer enhanced visual appeal, prolonged shelf life, and more cost-effective packaging. Let’s explore the benefits of using shrink wrap for food packaging, the different types of packaging it offers, and the best shrink wrap machines for different types of food.

Types of Shrink Packaging for food

There are two primary types of shrink packaging for food items:

1. Primary Packaging

Hard fresh produce like cucumbers and cabbages, as well as frozen food items like pizza, can be directly shrink wrapped. The shrink wrap serves as the primary packaging, directly in contact with the food products.

2. Secondary Packaging

For soft or fragile food items like bread and fruits, a primary container or tray is used for protection, and the shrink wrap acts as secondary packaging. Similarly, instant food boxes can be shrink wrapped to create a single, secure packaging solution. It holds the primary container securely in place and provides an additional layer of protection during transportation.

The Best Shrink Wrap Machines for Food

Selecting the right shrink wrap machine is essential to ensure efficient and effective packaging and cost-saving in the long term. We highly recommend you consult with our experienced packaging machine experts for personalized recommendations based on your food items. Take advantage of our free packaging consultation by clicking here. In general, three distinct options are available for food shrink wrap machines: Hood sealers(also known as one-step sealers), L-bar sealers + Shrink tunnels, and Side sealers + Shrink tunnels. Below are our recommended top models for different scenarios:

If your product is not too big and small quantity, hood sealer is perfect for entry level shrink wrapping. There’s no need to purchase a heat shrink tunnel, as this is a one step solution to shrink wrapper products.

Bundle Wrappers are extremely versatile and perfect for packing glass, PET bottles, cans, boxes, trays, jar, and cartons of different sizes in a wide range of pack collations. They can be used in several industry segments, for example, Beverages, Food, Chemicals, wine and spirits, cosmetics, wood, textiles, graphics, etc.

Our semi-automatic L Bar Sealers are the perfect machines for low to medium volume shrink applications.  An operator sets the seal time and heat, then inserts a product between the two layers of center folded shrink film, then presses down on the sealing bar. Once the seal is complete, the package is pulled away from the seal area.

Automatic L-bar sealers are perfect for center-folded shrink-wrap applications, where speed is a factor. They use center-folded shrink film, a conveyor feeds the product into the film and into the sealing area. Vertical/horizontal photocell sensors determine when to activate the jaw sealer. Once the product is sealed, a conveyor automatically feeds the sealed product into a shrink tunnel.

 Side sealers can come in intermittent motion and continuous motion designed to wrap packages effortlessly and efficiently.  Side Sealers with continuous motion are the fastest type of sealers which are suitable for wrapping box type packaging.

Shrink Tunnels are used with sealers to apply heat to the film so the film shrinks perfectly around the product.  They can come in two different conveyor configurations: Roller or Belted. Both conveyors can be used with polyolefin, PVC sleeves, and polyethylene films. The space between these rollers allows hot air from the bottom to shrink the film around the product to create a tight sealed package.

Lowest Cost Beer Can Packaging: No Corrugated!

Overview:

A craft brewer wanted to reduce their material costs by 60%, increase production by 300%, and eliminate manual labour. They were wrapping cans in a printed cardboard case and were looking to wrap both supported and unsupported cans in clear or printed shrink film with or without trays.

An Impak technical application expert worked with the craft brewer to get a better understanding of their expectations and recommended a highly efficient automatic shrink wrapper with an automatic infeed.

Since the implementation of the new shrink wrapping system, the brewer has reduced their packaging cost by 60% and reallocated labour to other key areas of their operation.

Challenge:

The Brewer had a tight budget and needed the equipment quickly. They wanted to cut their packaging costs by replacing printed cardboard cases with printed film while at the same time increase their production speeds. Their current process was very labour intensive. Production was under significant pressure from sales to deliver more product immediately.

Looking to Reduce Material Costs of Beer Can Packaging?

Process & Solution:

The craft brewer and Impak’s applications expert worked together to find the best solution. Three different options were considered. Impak combined several configurations and then proposed a system that ran at 30% over the required speeds and fit within the customer’s budget.

The solution enabled the craft brewer to shrink wrap their unsupported cans in 6 packs, 12 packs or 24 packs in printed or clear shrink film. With a quick changeover, the system can also wrap printed or clear shrink film around trays OR run trays through without wrapping them. The automatic bundle wrapper was delivered on time. To help the customer get through their immediate production surge Impak was able to supply a semi-automatic bundle wrapper on a rental basis until the system ordered was delivered and installed.
