Iberplast invests €2m in materials handling

Colombian packaging producer Iberplast has installed a €2m materials handling system from Motan-Colortronic at its new beverage packaging factory at Bogota, which commenced operation at the end of last year. The project included

internal and external material silos and a centralised vacuum materials handling system controlled by Motan-Colortron- ic’s VisuNet central control. The installation supplies all

the injection moulding and extrusion blow moulding equipment at the Iberplast facility. The contract includes nine

Gravicolor 600R gravimetric gain-in-weight dosing and mixing units for handling virgin and recycled PET in preform production and a further nine Gravicolor 300 units for dosing and blending virgin and regrind PE. Each of the 300 units is equipped with a C-Flex M pigment dosing unit.

According to Motan-Color-

tronic, the conveying system had to be adapted to function at Bogota’s altitude of 2,600m above sea level. Iberplast manufactures PET

preforms, bottles and closures, bottle crates, and large blow moulded polycarbonate water bottles. The company operates a range of processing equip- ment, including machines from Husky and Sacmi compression moulding systems. ❙

Bericap adds 33mm hot-fill option

Bericap has introduced a new line of hot fill closures for 33mm neck finishes that eliminate the need to use an aluminium foil sealing membrane. The new closures are available in flat screw or as PushPull

sport closures. Both feature Bericap’s DoubleSeal system, which ensures a leak-free seal while simultaneously stabilising the bottle neck during hot filling. Bericap says this allows the use of neck finishes down to 1.5mm thick. According to Bericap, adoption of a 33mm closure and neck finish can result in a material saving of up to 39% compared with a standard 38mm closure. Bericap has also added a 33mm DoubleSeal

closure option for aseptic packaging applications currently using a 38mm type. ❙

Surlyn delivers cosmetic appeal

Korean cosmetics firm AmorePacific used DuPont’s Surlyn polymer and an overmoulding technique to create a novel new pack for its Sulhwasoo Dahansul range of premium skincare creams. The encapsulated label

effect is created by first printing onto a polyamide inner container before overmoulding it with Surlyn. By creating a completely solid part with no gaps between the inner and outer walls, light refraction is eliminated to allow clear display of the decoration. According to DuPont,

the premium nature of the product is enhanced by the high quality visual appearance together with the pleasant tactile surface of the ionomer resin. More information about overmoulding with Surlyn for cosmetics applications can be found at ❙
