SentryGlas film from DuPont is produced in rolls with a maximum of 1.83 m wide by 0.89 mm thick. We offer with our technology the welding and cutting of SG- rolls to any width and call it SG-jumbo. Until now sheets of basic roles in widths from 2.36 m to 3.28 m (3.58 m) are available.
SG-jumbo can be processed in conventional lamination equipment. A limitation of your laminates in the width or the length is history. In addition, we offer to cut the foil to the correct width. According to customer requirements to the total film length.
In order to produce a continuous weld joint of us a patented welding process has been developed. The weld produced represents a firm, elastic and resilient connection between the two films.
The weld seam has a comparable strength as the SentryGlas film itself and is usually machinable. The welding technology has been extensively tested with the common lamination methods.
We treat the rolls with the utmost care, it is simply „wrapped " and cannot be damaged or soiled.
We offer our customers the opportunity their rolls to be tested for its moisture content, Carl-Fischer titration. The rolls are not assessed by us for their laminatability, dirt or damage through. Abnormalities of the film or the packaging we share with our customers, of course, immediately.
SG- jumbo and only cut sheets are to be processed by the processor for SentryGlas according to the recommendations of Dupont. We disclaim any liability for the information necessary for lamination film properties themselves, a contamination of the film with particles that damage the film or for products especially laminates of films or from SG- jumbo.
We guarantee the properties of the weld, but not to the laminated weld. The laminatability of the weld has to be ensure by the customer by laminates. They should be checked by the customer for new or changed lamination processes or modified laminate structures by test laminates. Please take note of our general terms of Conditions on our web side.
The sheet is fixed with an adhesive tape to the winding core, so that this contact surface will be approximately 50 mm over the entire width. Don not used this contaminated Foil in any case. When welding is produced in the width of the rolls, over the entire length of roll a blend of about 80mm must be accepted. At the end of the roll there is 1m not welded. producible SG- jumbo roll formats [m ] of standard roles
|Basic Roles||Possible Width||Roll lenghth|
|1,53+1,53||2,98||197,5 (+2,5); 47,5 (+2,5)|
SG jumbo is usually wound onto a new core and correspondingly a longer one made of PVC. If no corresponding long winding core is delivered by costumer, two different standard lengths can be purchased from us (2850mm and 3450mm). Hubs may optionally be replaced with a comparable core.
If the film is delivered in crates from Du Pont, we can assemble it into a long box. Or send us boxes from other manufacturers too, for example in Reusable box. Please always in consultation with us.
We support our customers from the very beginning, independent and cost- oriented, from choosing the right equipment to process optimation with an experienced team.
