cessing techniques and material require-

ments. Packaging can exhibit multiple

functions including high barrier, boiling

tolerance, UV-ray resistance, high preser-

vation ability, selective ventilation proper-

ty, high temperature resistance, anti-mi-

crobial, anti-corrosion, deodorization,

shape memorization, easiness of re-clo-

sure are particularly in high demands.

To fulfill all these functions, film making

technology evolves quickly to extrude mul-

tiple layers and integrate them seamlessly

with the latest co-extrusion technology.

For example, German Kuhne Anlagenbau,

also CHINAPLAS 2015 exhibitor, has part-

nered with DuPont to launch TripleBub-

ble

1 water quenched and bi-oriented film

technology. The new co-extrusion techno-

logy can provide up to 11 layers of functio-

nal polymers, in 20-110µm thickness and

the elasticity up to 60%. It demonstrates a

good balance of puncture resistance, flexi-

bility, softness, seal performance, transpa-

rency, and shrink behavior while saving

raw materials up to 50% over conventio-

nal laminate structures.

Sustainable packaging has drawn a lot of

attention in the market amid the rising

awareness of environmental protection

and imposing global and national legisla-

tions on wastes management. Sustain-

able packaging can be achieved mainly

through minimization of packaging, re-

duction the packaging weight, and facili-

tating the reuse and recycle of end-of-

the-life products.

Thinner and lighter packaging can signi-

ficantly reduce the disposal wastes.

Taking film as an example, the material

Plastics packaging has occupied over

30% of share in packaging market,

thanks to its outstanding properties such

as lightweight, versatile, anti-corrosive,

anti-abrasive, and easy to process proper-

ties and more that other materials cannot

match. In the next few years, safe, envi-

ronmentally friendly, lightweighted, mul-

ti-functional and intelligent packaging

will remain in mainstreams. Packaging

products which feature multiple charac-

teristics such as anti-microbial, high tem-

perature resistant, UV-ray resistant, high

barrier, biodegradable and recyclable will

be at market's focus.

Many of the key players involved in ad-

vancing these materials and processing

technologies will be among those exhibi-

ting in

Leading players in plastics packaging

over the world are flexing their muscles

to push the technologies into limits in or-

der to meet the consumers' needs in this

fast changing packaging world.

According to a report of Freedonia, food

and beverage, and medical sectors will

be the key drivers for the strong demand

of packaging products in 2016. These

two sectors require high standard of pro-

flexibility, viscosity and easiness to pro-

cess are key to make a thinner film.

DSM‘s recently launched modified polya-

mide Akulon XS which crystallizes much

slower in the film bubble than conven-

tional ones and hence gives processors

more leeway in their processing condi-

tions. The film is also more stretchable,

while offers exceptional mechanical

strength and durability.

Biopolymers are another way to reduce

the environmental impact. NatureWorks'

Ingeo, a plant sugar based polymer de-

rived from natural resource, can not only

be biodegradable but also maintain simi-

lar mechanical strength and heat resis-

tant property as the non-biobased poly-

mers. NatureWorks notes that manufac-

turers should not consider only the raw

material cost but the overall production

cost. As compared with PET, Ingeo con-

sumes less energy and save more cost by

being processed in low temperature en-

vironment.

Apart from reducing the wastes from the

source by using bioplastics, the advances

of plastics recycling technology can help

too. Optical sorting solution, for exam-

ple, can sort resin and pellets base on co-

lor, texture and shape and remove all

kinds of impurities such as discoloration,

stains, dye drops, etc, while extracting

pure and high-value materials. In respon-

se to the high demand for plastic wastes

management, CHINAPLAS 2016 will in-

troduce a new "Recycling Technology

Zone" with an aim to provide sustain-

able recycling solutions.

The packaging materials market is serving for a diversity of demands, such as

plastic products and films with high barrier, high strength, high temperature

resistant, anti-ultraviolet ray, anti-microbial and biodegradable properties
