Savvy Vietnamese Firm Launches All-PE Laminated Pouches
Thanh Phu’s ‘Veloflex’ converting technology results in packaging with optics similar to conventional laminated structures but is readily recyclable.
The company has produced commercial packages and pouches for feminine-hygiene and adult-incontinence products and baby diapers for both Japan’s Unicharm Corp. and Kimberly-Clark, New Milford, Conn. The company is also exploring an all-PE package for frozen uncooked seafood and other such non-barrier frozen applications to replace the current nylon/PE laminate.
Dam’s company produces conventional flexible packaging materials for Vietnamese seafood suppliers who pack the seafood under order from U.S., European, or North Asian buyers.
Thanh Phu is now looking for distributors to introduce its 100% PE/PE laminated products to the U.S. Depending on the potential partnership, Thanh Phu could supply the fully printed laminated pouches or film, or it could supply the film to a printer with downstream processing capability.
The company’s plant is outfitted with the latest blown film technology from Windmoeller & Hoelscher Corp. (U.S. office in Lincoln, R.I.). The latest of several lines, acquired at K 2013, is a Varex II with machine-direction orientation (MDO) technology installed in 2015.
Ditto for the latest printing technology from W&H: The firm operates Heliostar S gravure presses, the latest of which is a 2016 model.
Asked to characterize Veloflex laminates, Dam noted their very similar optics compared with OPP or PET/PE laminates, but explained that when a Veloflex film is stretched, improved clarity and stiff- ness result. Moreover, he touts the resin’s excellent processing, noting that his firm has run a 25-micron film with ±1-micron thickness deviation. He says this film has twice the strength of a conventional 50-micron coextruded lamination at half the thickness.
About 60% of most of Thanh Phu’s films are of mLLDPE, but for some products they will go to 80% or 100%. Because the film is very stiff and strong, gravure presses can be used to back-print the 100% PE pouches.
More recently—and jointly developed with ExxonMobil— Thanh Phu produced a 100% PE/PE laminated stand-up pouch, using Veloflex technology for Unicharm Vietnam.
Medical tubes are becoming ever smaller and thinner while adding new features like high-tech material combinations, more wire braiding/wrapping, and heat-shrink sheathing for strength and kink resistance.
One of the first applications for blow molded HDPE bottles was the replacement of glass for bleach packaging.
A new study shows how the type and amount of LDPE in blends with LLDPE affect the processing and strength/toughness properties of blown film. Data are shown for both LDPE-rich and LLDPE-rich blends.
