Types of shrink wrap machines

Shrink wrap machines are machines used to pack products with shrink films. They are an integral part of the modern packaging industry. According to how products are packed, what kind of films are applied, and how the wrapping process is carried out, shrink wrap machines can be divided into three categories:

• By products shapes and sizes:

  Specific shrink wrap machines fit particular shapes and sizes. For example, a tunnel shrink wrap machine is usually applied to pack flat products such as books, tiles, and fruit boxes. It is generally used with a horizontal shrink wrapping machine, which comes with various models to accommodate different sizes and shapes of products. Multi-head shrink wrappers are designed as modular systems to securely wrap products with multiple heads. Generally speaking, the more heads a shrink wrap machine has, the faster production lines it suits.

• By wrapping materials:

  A pad packaging machine, a type of shrink wrapping machine, uses a pad to pack items and is ideal for products that require extra protection or reinforcement during transportation. Also, depending on the product, some items may require special attention to ensure they are not damaged during the wrapping process. In this case, custom packaging solutions can be offered to incorporate unique inserts to protect the product while being wrapped.

  On the other hand, electronic shrink films are designed for flat or semi-flat products, often combined with an inter-folder system. This system can be used in various applications, such as separating and retaining products such as food and dairy products.

• By methods of film application:

  As previously discussed, the technology applies to films that vary, and specific shrink wrap machines work better with particular films. For instance, collar shrink wrap machines are ideal for cylindrical products with neck labels, bottles, and jars. They are suited for PVC and POF shrink films to provide tamper-evident packaging solutions.

  Another example is an inverted shrink wrap machine that applies heat shrink films invertedly. It is ideal for low-density polyethylene (LDPE) films and targets businesses that need efficient, eco-friendly packaging solutions. Additionally, banders are typically used to group items together or provide product visibility in retail settings. They are commonly applied with low-density polyethylene (LDPE) shrink film, which adheres to industry standards for shrink film materials. Depending on the model, configuration, and film type used, shrink banding machines can deliver shrink rates of up to 98%.

Specifications and maintenance of a shrink wrap machine

The specifications of a shrink wrap machine differ depending on the model and type. Here are some key specifications of the machines and the maintenance requirements.

• Machines have a pallet or package size they can effectively shrink-wrap. Testing samples before moving to full-scale production is important. The wrong fit can cause delays and frequently stopping the machines to adjust.
• There are limitations on the film and shrink film roll sizes that can be used with the shrink-wrap machine. A shrink tunnel machine will take a larger film rolls than an auto A fold machine, for example.
• Shrink-wrap machines use electricity, gas or heat from hot air coils or wires to power up and create the heat needed to shrink. Electricity requirements are listed in volts and amps, gas in BTUs, and heat in temp degrees. How the heat is generated and circulated determining package quality.
• Shooting mechanism: The type of shooting that releases the film in a shrink-wrap machine differs between manual and automatic models. In manual models, an operator pulls a lever to shoot the film. In automatic models, photocells or sensors detect the package to automatically shoot the film around it.
• Machines have panels and buttons that control and adjust film temperature, sealing time, pressure, shrinkage temperature, and mores. Machines vary how these function are controlled, sealed, and adjust from manual to digital and touchscreen controls.
• The strength, quality, and ability to prevent damage of the material used to construct packaging machines is crucial. Stainless steel, carbon steel, aluminum, and other materials offer different protective qualities and resist corrosion.

Maintenance requirement varies with the machine type and model. As a general rule, manufacturers advise:

• Regular Cleaning: Machines should be cleaned after use, especially the film residue that gets on the heat plates. Bacteria build-up from leftover food is a health hazard, and fires may occur if film residue ignites on heat plates.
• Locked and Alarmed Storage: When not using the machine, keep it locked and alarmed. A manual shrink wrap machine is more vulnerable to theft than automatic machines.
• Periodic Deep Clean: Do a deep clean on a scheduled basis.
• Calibrate and Inspect: Check for loose film, damaged parts, parts needed for replacement, and failing components. Calibrate the machine as needed.

Uses of shrink wrap machines

Shrink wrap machines have a lot of uses in various industries and sectors. They are ideal for packaging items in bulk or for holding together items that come in multiple units. Commonly, shrink wrap machines are used to package food products like pizza, meat, fruit, vegetables, and canned goods. The machines wrap the individual or multiple units of these products. What’s interesting about this is that shrink wrap machines help preserve the quality of these food items as well as prolong their shelf life.

Shrink wrap machines can be found in packaging facilities, warehouses, and assembly lines. Here, they are mostly used to package products for distribution and resale. In retail settings, products are often shrink-wrapped in units to make them easier to manage. Furthermore, shrink wrap machines are used extensively in the publishing industry to package books, calendars, DVDs, CDs, boxes sets, software packages, and other kinds of fragile and non-fragile media.

For clamshell packaging, shrink wrap machines are used to secure the product inside the clamshell. The wrap gives it a more appealing look on the store shelf while reducing the chances of theft. In the bundling industry, shrink wrap machines are used for bundling items together for convenience and ease of use. Examples of such items include magazines, catalogs, and promotional materials.

Another typical use of shrink wrap machines is to package non-pourable liquids. When it comes to items such as bottles, jars, and cartons, shrink wrapping offers additional handling safety and reduces spillage.

Lastly, shrink wrap machines are ideal for packaging perishable items like meat, poultry, and seafood. They are typically refrigerated or frozen to keep the product cold. In the pharmaceutical industry, shrink wrap packaging is used to secure and protect medication containers such as bottles, blister packs, and boxes.

How to choose shrink wrap machines

It can be quite easy to select the appropriate shrink wrap machines for products when a few essential things are taken into consideration.

• Product dimensions:

  The size and shape of items searching to be packaging with shrink wrap are vital factors when selecting a shrink wrap machine. Particular models are made to suit diverse product dimensions and shapes. Buyers should measure and evaluate their product dimensions to ensure they select a shrink wrap machine with the suitable size of the shrink tunnel or chamber.

• Packaging needs:

  Packaging requirement includes packaging style, film type, and shrink speed. Buyers should consider if they need to achieve a center-value shrink wrap as a retail packaging or a secure packaging, the kind of film they intend to use, and the needed shrinks' speed and productivity. This could help them to select a shrink wrap machine that suits their packaging requirements.

• Operating environment:

  The operating setting plays a critical role in determining the suitable shrink wrap machine. If one's environment is prone to dust or other contaminants, one might consider a changeable film frameless machine, such as a fully automatic shrink film machine with a conveyor belt, which is operated with an opaque film faceless of the machine, forward, backward, and sides. Furthermore, if one's job environment does not have access to electrical power, a battery-powered shrink film machine can be a feasible option.

• Budget:

  Buying a shrink wrap machine entails a lot of investment, and budget is among the most crucial aspects to consider. Buyers should set a reasonable budget based on their packaging needs and refrain from placing too much emphasis on additional features and functions. Researching and studying various models' prices and specifications can be helpful in selecting one that suits one's budget while also meeting packaging needs.
