VERISAFE SHRINK FILMS / FLAME RETARDANT SHRINK FILMS
VERISAFE FLAME RETARDANT SHRINK FILMS are the highest certified shrink films on the market today and comply to and exceed all industry standards in this area
Some shrink films on the market today claim to meet the EN 13501
test which is the standard European reaction to fire classification and CE marking for permanent installation in buildings where applicapable, and may also meet UK & Irish buil;ding regulations dependant on application. However this classification is NOT
third party certification and cannot be taken as being equivalent to the LPS CERTIFICATION
( Loss Prevention Certification Board ) 1207 & 1215 which is the standard required by many Irish & UK insurers and specifiers for temporary protection materials used in buildings under construction or undergoing renovation/ scaffoldings etc.VERISAFE FILMS
are authorised to use the LPCB mark LPS 1207 and 1215 on their Flame Retardant films having complied fully with the requirements & yearly Audits for the LPCB approval for listings of Protective covering materials / issue 2 and also issue 3 / Listing for Scaffold claddingLPS 1207
is quoted in the infires/FPA document - Fire Protection Construction Sites; joint code of practice on the protection from fire of construction sites and buildings undergoing renovation ( seventh edition may 2009)VERISAFE FILMS
also hold certification DIN
4102 / building material Class B1 / the material has met the demands for Non - readily ignitable building materialsPLEASE CONTACT US FOR COPIES OF ALL CERTIFICATIONS REGARDING VERISAFE INDUSTRIAL SHRINK FILMS

Shrink Film is determined by the resins and additives used, the extrusion process and the extrusion and associated equipment. Not all shrink films are created equal. The key ingredients of a quality shrink film, is the type of resin, the additives of EVA, UVI and anti-block. The extruder used to make the blown film has a die where the gap and its concentricity keep gauge tolerance within parameters. Other parts of the equipment include the winder that takes the collapsed film, gussets and/or folds it, and puts it on rolls of certain widths and lengths.
The material(s) used to make shrink film must be 100% fractional melt virgin resin(s), that is not reprocessed material, with a primary mixture of low density polyethylene (LDPE) and a secondary mixture of linear-low density polyethylene (LLDPE). To achieve a balanced shrink (50 to 60% in the machine direction (MD) and 40 to 50% in the transverse direction (TD), and an overall shrink of 25%, the base resin should have a. 25 melt-index. A light stabilizer (ultra-violet inhibitor/UVI) of the hindered amine rather than the benzephenone type gives the shrink film its outdoor service life expectance. An EVA (ethyl-vinyl-acetate) additive gives the shrink film flexibility, greater puncture resistance, greater toughness and deters splitting and brittleness in high winds and extreme cold weather. An anti-block agent (slip) prevents the film surfaces from sticking together during the manufacturing process and allows for easy unroll/unfold from the roll by the user. Excess or low quality anti-block material will cause the film surface to feel oily and prevent tape from sticking to the surface or film-to-film-fusion. Colour additives are used to give the shrink film a blue or white tint that should result in a minimum 65% opacity.
The extrusion process, starting with the blending of the resins and additives, their melting and passage through the die determines the mechanical attributes of quality of the shrink film. After exiting the die the film goes through the air cooling ring and travels up to the guide rolls, where the film bubble is collapsed and flattened and then goes to the winder where it is put on rolls. This mechanical process will determine such quality factors of film thickness, gauge control within required tolerances, homogeneity where resins and additives are equally dispersed and the film is "balanced" and no physical damage.To Visit Verisafe Website click on the link below.........
