General
To make shrink film for scaffolding the resin must be a 100% fractional melt virgin resin that is not reprocessed / recycled material, with a primary mixture of low-density polyethylene (LDPE) and a secondary mixture of linear-low density polyethylene (LLDPE).
A light stabilizer (ultra-violet inhibitor/UVI) of the hindered amine gives the shrink film a minimum service life of 1 year.
After project completion, the shrink wrap can be cut from the scaffolding and bundled for recycling. Scaffold shrink wrap is much easier to recycle than traditional scaffold sheeting because it does not have any extra reinforcing, eyelets etc. to contaminate it. Shrink wrap is manufactured from 100% virgin LDPE resins and nearly every waste company will welcome it for recycling and should be able to provide you with documentation as evidence that you have disposed of it in a responsible way. As always, contact us if you need assistance.
Recycling
Unless you have very large quantities, then it is unlikely that a recycling company will pay you for scaffold shrink wrap, however, for a company that values high quality LDPE they may take it for a small administration fee to cover the necessary paperwork.
In order to engineer a shrink wrap film with the mechanical properties and consistency needed for demanding construction applications it is not possible to reuse recycled materials for manufacturing.
Shrink wrap is heat shrunk ‘drum tight’ so that it moulds very tightly around the sides and roof of a scaffolding structure. However, it is not possible to shrink the sheeting twice which means that once it has been removed from the scaffolding it must be collected for recycling.
Training
We can provide training on a temporary structure at your yard / premises or on a ‘live’ job. No classroom is required as the course is based mainly on assessment of practical skills.
We find a ratio of 4 trainees to one trainer is ideal but up to 6 is OK.
An initial training session on a small scaffolding structure at your site for a team of 4 will typically last 4-6 hours. ‘Live job’ training generally lasts longer and may be a full day depending on your requirements.
Certification is based on a practical assessment of shrink-wrapping skills by our trainer and a short multiple-choice test. This practical assessment and scoring are the system we use for training our own installation teams. Once completed, we provide copies of these records and certificates so that you can provide evidence of the competencies of your team to your customers.
We can supply an individual trainer or a small team to work alongside your team on a ‘live’ job which means that your team receive training and the knowledge to start working independently.
We work with customers from all over the world and regularly provide shrink wrap training outside of Denmark. Let us know where, when and how many people and we will get back to you with costs immediately.
Welding and shrinking are the two main skills required to carry out almost any scaffold encapsulation and containment job. These skills can be taught in an hour or two. The challenge of shrink wrapping (and also the benefit) is that because it is so versatile – it can be used on the roofs / sides of any shape and any sized scaffold, every project is a little different and ‘custom’. Therefore, it is one of those skills that develops with practice and experience to a variety of projects over time. That is why our trainers are time served members of our own installation teams so they can impart valuable real-life knowledge to your teams and not just the theory.
Installations
Ideally 1-2 weeks’ notice is great, but we understand the nature of certain projects means that you may not always have this much notice so we will always try and be flexible to meet your deadlines.
Yes, however electric guns are available but they require three phase electricity supply, are cumbersome to use, cost three times as much and are still only about 1/3 of the power so the job will take much longer.
Our standard warranty for shrink wrap that we install is 25 weeks subject to wind speeds up to and including 47mph.
We work on a 100m2 per man per day for scaffolding encapsulation & containment sheeting.
