LDPE (Low-density polyethylene) as a film resin nowadays has been widely used in food, industrial and consumer packaging. AdsaleCPRJ.com is honored to invite Dow Chemical's Sudjali Halim, Marketing Manager, Basic Plastics, Asia Pacific, to share with us the latest market information and innovations of LLDPE (Linear low-density polyethylene) and ULDPE (Ultra Low-density polyethylene).

SH: Mr Sudjali Halim

CPRJ: What are the applications of ULDPE? Comparing to LLDPE, LDPE and HDPE, ULDPE has much fewer brands and fewer products, why?

SH:
ATTANE™ ULDPE Resins is in Dow Chemical's ULDPE product family. This product offers much higher physical and sealing properties. They are targeted at the packaging films requiring special puncture resistance, cold temperature impact and a very low temperature sealing performance such as in the higher speed packaging.

ULDPE resins are much lower in density than conventional LLDPE. They are targeted at a more niche market where the performance requirements for the products are different from that of the general packaging industry. This is why the demand for ULDPE is not as widespread as for the other resins such as LLDPE thus the reason for fewer brands and products.


CPRJ: Concerning the DOWLEX™ NG LLDPE NG and ATTANE™ NG ULDPE introduced by DOW, what are their processability and performance as when comparing to conventional brands? Are there any supporting figures, table or research founding available?

SH:
DOWLEX™ NG (Next Generation) LLDPE and ATTANE™ NG ULDPE are manufactured via proprietary solution processed using octene comonomer. These resins have very good processing properties compared to conventional resins.

Based on our improvement on Ziegler-Natta catalyst, our new DOWLEX NG LLDPE and ATTANE NG ULDPE can now offer improvement on films manufactured with the resins. In terms of dart impact, the new resins can offer more than 300% improvement compared to the conventional LLDPE equivalent. In term of optics, the new resins can reduce the haze of the films by more than 50%.

Some exceptional benefits that existing film converters can look forward to from these new film resins as compared to conventional brands include:

  • Exceptional optics without loss of physicals - better clarity and gloss to help converters differentiate their films and make their products stand out in a crowded marketplace.

  • Lower energy costs – due to improved processability.

  • Supports development of clearer films – welcomed by brand owners wanting to make their products stand out.

  • Measurable down-gauging potential - lower weight/less product needed for same/better performance which equals to greater cost savings/more sustainable packaging solutions


  • CPRJ: What are the areas of application targeted to these resins?

    SH:
    These new film resins are targeted for use in food and specialty packaging, industrial and consumer packaging, and health and hygiene applications.


    CPRJ: How’s the LLDPE market affected by the financial crisis?

    SH:
    In general the demand in several market segments, such as food and specialty packaging, industrial and consumer packaging, and health and hygiene applications are still growing strongly in Asia. The industry has also been looking for new materials that offer better optics, improved toughness and faster processing opportunities, so our new products would offer what the market needs.


    CPRJ: In what ways the new LLDPE plant (developed jointly by Dow and Siam Cement) will help to promote the sales of LLDPE in Asia?

    SH:
    Our new plant would be able to manufacture various products and additional volume to support the growth of our customers in Asia. By being close to the market we can shorten our response time to deliver our products and function as a local supplier to Asian countries. It is also a sign of our long term commitment to Asian market


    CPRJ: How do you access the growing potential of LLDPE in Asia Pacific and also in China?

    SH:
    Asia in general will grow stronger than other markets from across the globe. We have key growing countries headed by China which will still have strong demand of LLDPE in the coming years. Also India and ASEAN countries such as Indonesia and Malaysia are also sizable markets that cannot be ignored in terms of LLDPE consumption. These countries will basically support the growth of LLDPE demand in Asia in the coming years.
