An automatic shrink wrapping system is a packaging system that feeds products into the machine automatically. It then wraps each item in shrink film, seals the film and sends the pack through a heat tunnel.Inside the heat tunnel, the film contracts tightly around the product. This produces a neat, secure package while reducing manual handling.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 maintain steady packaging quality during long production runs.What Is the Automatic Shrink Wrapping Process?Most automatic shrink wrap machines use a similar packaging process, even when their designs differ.1. Automatic Product FeedingProducts enter the machine by conveyor or through an integrated production line.2. Shrink Film PositioningEach product is surrounded by shrink film before it reaches the sealing section.3. Sealing the PackThe machine forms a precise seal around the product.4. Heat TunnelHeat is applied as the pack moves through the tunnel, tightening the film around the product.5. Pack ExitThe finished pack leaves the machine ready for storage, transport or retail display.What Are the Benefits of Automatic Shrink Wrap Machines?Businesses use automatic shrink wrap machines for several practical reasons.Faster ProductionAutomatic machines can package far more products than manual equipment. This makes them suitable for medium- and high-volume production lines.Repeatable ResultsEvery pack is wrapped using the same machine settings. This creates a reliable and repeatable pack appearance.Lower Operator InvolvementStaff are not required to carry out every stage manually. Employees can then spend more time on other tasks.Better Product ProtectionShrink film can help protect products from dust, moisture and tampering during warehousing and delivery.Lower Film WasteCurrent machinery often includes controls designed to limit excess film consumption. This can limit wasted material without weakening the seal.Where Are Automatic Shrink Wrap Machines Used?Many sectors use automatic shrink wrapping equipment to package goods quickly and consistently.Typical sectors include: Food manufacturing Drinks and beverages Household goods Books, magazines and other printed goods Pharmaceutical products General consumer products Industrial components Grouped retail packs 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.You may need an automatic machine if: Employees spend a large amount of time wrapping products manually Your required output is increasing Pack consistency varies depending on the operator You need greater output without adding more labour Products need to be wrapped continuously For businesses with rising volumes, automation can provide steadier output with less operator input.Key Features to Check Before BuyingDifferent businesses need different machinery, so the correct system will depend on your products and production process.Points to check include: Maximum operating speed Maximum product dimensions more info A reliable sealing system Suitable film types Adjustable temperature controls Conveyor integration Straightforward machine controls Servicing and maintenance needs Some systems can also be customised for unusual product dimensions or specialist packaging tasks.How Do Automatic and Semi-Automatic Machines Differ?With a semi-automatic machine, an operator usually has to place the product or begin one or more stages.Automatic systems handle almost the entire cycle with limited operator involvement. They are therefore more appropriate for high daily packaging volumes.The main results are higher throughput, greater consistency and less operator involvement.How Fast Can Automatic Shrink Wrap Machines Operate?The number of packs produced per minute depends on product dimensions, equipment settings and the type of wrap required.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.

Automatic equipment can often be configured to handle several product formats. 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 processes begin limiting daily output.Do automatic shrink wrap machines reduce packaging costs?Cost savings may come from reduced manual work, steadier production and less wasted film. The machine must be specified according to the required packaging process.Can automatic shrink wrap machines use sustainable films?Some automatic machines are compatible with recyclable, recycled-content and selected compostable shrink films. Suitability depends on the type of film, pack format and machinery specification.
