An automatic shrink wrapping system is a packaging system that automatically receives products from a conveyor or production line. It then covers the product with shrink film, seals the film and sends the pack through a heat tunnel.The heat tunnel causes the film to shrink closely around the item. This produces a neat, secure package while limiting the amount of manual work required.Where manual equipment depends heavily on an operator, automatic machinery is made for continuous output. Once the correct settings have been entered, the equipment can wrap products repeatedly using the same settings.What Is the Automatic Shrink Wrapping Process?The exact machinery may vary, but the basic shrink wrapping process is usually similar.1. Automatic Product FeedingA conveyor automatically carries products into the wrapping equipment.2. Film WrappingThe machine places shrink film around the item ready for sealing.3. Automatic SealingA sealing system joins the film securely around the item.4. Shrinking the FilmThe wrapped item travels through a heat tunnel where the film shrinks.5. Pack ExitOnce wrapped, the completed product exits the machine and can be stored, distributed or displayed.Why Use an Automatic Shrink Wrapping Machine?There are several reasons why manufacturers choose automatic shrink wrapping equipment.Higher Packaging SpeedsAutomatic machines can package far more products than manual equipment. This makes them suitable for medium- and high-volume production lines.Consistent PackagingEvery pack is wrapped using the same machine settings. This creates a neat and uniform appearance.Less Manual HandlingThe machinery reduces the amount of hands-on packaging work. Employees can then spend more time on other tasks.Added Protection During DistributionThe wrapped film provides a barrier against dust, moisture and interference during handling, storage and transport.Lower Film WasteMany modern machines include settings that reduce unnecessary film use. This can reduce waste while retaining reliable seals.Common Uses for Automatic Shrink Wrapping EquipmentAutomatic shrink wrap machinery is used across many industries because it combines speed with consistent pack quality.Common applications include: Food production Drinks and beverages Domestic products Books, magazines and other printed goods Pharmaceutical products Consumer goods Manufactured components Retail multipacks The equipment can be configured to wrap single products, promotional bundles and grouped goods.When Is It Time to Move to Automatic Shrink Wrapping?Companies often begin with manual or semi-automatic systems before upgrading when output rises.Signs that it may be time to upgrade include: Employees spend a large amount of time wrapping products manually website Production volumes are continuing to rise Packaging quality differs between operators You need greater output without adding more labour Products need to be wrapped continuously Automatic machinery often becomes more efficient as packaging demand increases.Key Features to Check Before BuyingMachine selection should be based on product size, output targets and packaging requirements.Useful machine specifications include: Production speed Supported product sizes A reliable sealing system Suitable film types Controllable tunnel temperatures Compatibility with existing conveyors Straightforward machine controls Servicing and maintenance needs Some systems can also be customised for unusual product dimensions or specialist packaging tasks.Automatic Versus Semi-Automatic Shrink Wrapping MachinerySemi-automatic systems depend on staff to carry out certain parts of the packaging process.Automatic systems handle almost the entire cycle with limited operator involvement. They are therefore better suited to businesses producing hundreds or thousands of packs each day.The main results are higher throughput, greater consistency and less operator involvement.How Many Packs Per Minute Can an Automatic Machine Produce?Production speed varies according to product size, machine layout and packaging complexity.Many automated shrink wrapping machines can produce approximately 25 to 40 packs each minute. Some high-speed automatic side sealers can produce over 100 packs each minute when the application permits.Kempner Automatic Shrink Wrapping SystemsKempner UK has supplied packaging machinery and shrink wrap materials for more than 50 years.

Many systems allow operators to change settings for different pack dimensions and product types. However, changeover times depend on the machinery.Are automatic machines only for large manufacturers?Yes, particularly when a smaller company is increasing its output. Investment often becomes worthwhile when manual packaging starts to restrict production.Do automatic shrink wrap machines reduce packaging costs?They can reduce labour needs, improve efficiency and limit film waste when correctly specified. The machine must be properly selected for the products and production targets.Are automatic machines compatible with recyclable shrink film?Many current machines can use recyclable films, films containing recycled material and certain compostable options. Suitability depends on the application and equipment settings.
