Flow Wrapping (Horizontal Bagging)

What is flow wrapping?

Flow wrapping is a high-speed and cost-effective packing method that wraps solid products into air-tight film bags.

Products are pushed through a conveyor belt, where they are wrapped in plastic film and sealed at both ends, with a seam across the back of the bag. This automated process lends itself to speed and efficiency, packing up to 70 bags per minute.

Flow wrapping is also known as horizontal bagging, pillow-pouch wrapping, fin-seal wrapping and crimp-seal wrapping.

What products are suited to flow wrapping?

Flow wrapping is suited to solid items of the same size and shape, due to the automated process on the conveyor belt.

Robust plastic bags keep products fresh, making horizontal bagging ideal for food products, including chocolate bars, biscuits, snack bars and cakes.

Flow wrapping is also suited to any high-volume packing project, including promotional item runs and samples.

Other products suited to flow wrapping include:

  • Leaflets
  • Scratch cards
  • Tissues
  • Toys and accessories
  • Products that need to be bundled together

Benefits of flow wrapping

Flow wrapping is a time and cost-effective packing method. At WePack, we’re able to pack up to 70 bags per minute and typically handle projects of between 2,500 to 500,000 bags or more – making us the ideal partner for your high-volume packing projects.

Horizontal bagging also keeps contents protected, thanks to robust plastic film and an air-tight finish, which locks products in place and restricts movement. Combining flow wrapping with gas flushing processes also removes oxygen from the bag as it’s packed, keeping food items fresh until they reach the consumer.

Plus, flow wrapping services are designed to fit perfectly around your products, with space-saving tails on either side, minimising material waste.

Additional benefits of flow wrapping include:

  • Cost-effective for creating promotional items or samples
  • Air-tight for neat and space-saving packages
  • Ideal for products that require clear brand visibility
  • Bags typically weigh less than alternative packing methods

Size and finish options

Flow wrapping bags can be rectangular or square, depending on your needs, and come in a range of sizes. Our bags can be produced from 15mm to 150mm wide and from 25mm to 160mm in length.

Bags are created from a robust plastic film and can either be ordered in plain colours – including opaque for full visibility over products – or fully printed brand designs, so they’re ready to hit the shelves straight from our facility.
