If you or your company uses PVC shrink film to shrink wrap your products, today you are in luck – Today we are not only going to be discussing retail shrink wrapping, but also offering great tips and advice to all to ensure that everyone is using the best and most appropriate machines and getting the most out of them too.
Shrink Wrapping Tips
- If you are looking to wrap your products in the ultimate way, you need to ensure that you choose a high quality film. Your wrapping can only be as good as the products which you use. The main two types of shrink film as PVC and POF – look into each of these before you make your decision.
- You also need to consider shrink film thickness and strength, with many available including: cross linked films, non-crossed linked films, soft shrink films, anti-fog-film, hot slip films and high performance films. What you are wrapping will enable you to choose which to use.
- Seal quality is also something that you need to think about – Seals must be strong and must not contain holes.
- Air holes are sometimes needed in shrink films – and for best results you should choose a machine which creates these for you so that they are consistent and exactly how you need them to be.
- You must also use a high quality shrink wrapping machine/tunnel. When looking for a machine to assist your company features that you should search for include: high velocity air flow, adjustable air flow patterns to direct air at the package, variable speed conveyor, accurate temperature control and love roller conveyor designs.
- Ensure that you are using the correct temperatures and times. Generally shrink wrap tunnels should be set to 150 degrees for example for POF film. If you are ever unsure regarding how to wrap a particular product you should speak to your shrink wrap machine/film supplier whom should be more than happy to advise you.
- Watch products as they come through your shrink wrap machine. Upon entry into the shrink tunnel the shrink film should balloon but should not burst. It should then slowly shrink down slowly and shrink wrapping should be completed when your product leaves the tunnel. If your film does not balloon, or if it bursts, there is obviously a problem and you should stop shrink wrapping until you have determined what it is so that you don’t waste any film.
These are only some of the available tips too. Upon purchasing or hiring a machine you should always read instruction manuals thoroughly so that you know exactly what you’re doing.
