When it comes to hand wrapping with stretch film, there are a few proper techniques you should follow to ensure a secure and stable load. Here are some tips to keep in mind:

1. Start with a Clean and Dry Pallet

Before beginning the wrapping process, it’s crucial to make sure the pallet is clean and dry. Any debris or moisture on the pallet can cause the film to slip or tear, which can compromise the stability of the load.

2. Use the Right Amount of Film

Using too little film can result in an unstable load, while using too much can be wasteful and costly. It’s important to find the right balance and use just enough film to secure the load without overdoing it.

3. Apply Tension to the Film

Proper tension is key to achieving a secure wrap. Too little tension can result in a loose load, while too much can cause the film to stretch and tear. Applying even tension throughout the wrapping process will ensure a stable and secure load.

4. Overlap the Layers

Overlap the layers of film by at least 50% to ensure complete coverage of the load. This will help prevent any gaps or weak spots in the wrap that could lead to shifting or damage during transport.

5. Seal the Edges

Sealing the edges of the wrap is essential to prevent the film from unraveling during transport. Be sure to wrap the film around the edges of the load and tuck it under the previous layer to create a secure seal.

By following these proper techniques for hand wrapping with stretch film, you can ensure a secure and stable load for transport.

Safety Precautions for Hand Use
