Food composite packaging film tends to be multi-functional, light and thin
In terms of special materials for functional food packaging, my country's R & D and production capabilities are still relatively weak. In the future, the food industry will continue to increase the demand for functional films such as high barrier, cooking resistance, UV resistance, light protection, antibacterial, breathable, and oxygen insulation. At the same time, there is a trend towards light and thin development.
Exxon Mobil Launches Edge at K Show 2016™XP two new grades, further expanding its product range. These new grades are suitable for shrink flexible packaging and food composite packaging, providing significant performance advantages for film processors and end users.
XP has been very popular in the market since its launch, and customers have reported that the performance level of the product has been upgraded to a new level. These new grades reinforce this positive effect. Edge XP 6026 and Edge XP 6056 have excellent processing properties, which can provide stronger toughness, anti-rubbing properties, heat sealing properties, balanced shrinkage and good optical properties. For processors, the high melt strength of these polymers allows for greater bubble stability and increased throughput.
Food packaging film produced by the new brand of Edgel XP.
The excellent toughness and heat-sealing properties of food packaging films (including large and small packages) produced by the new Edge XP brand help brands protect frozen or dry food, meat and cheese products from production to consumption. The melt strength and toughness of Edge XP can reduce film thickness while maintaining high performance. Processors can take advantage of the extraordinary performance and processing capabilities of these Edge XP grades to simplify product inventory and reduce costs.
With the increasing public awareness of reducing food waste and extending the shelf life of products, the demand for barrier films for food flexible packaging has begun to show a continuous upward trend. Nowadays, most barrier film products are often co-extruded through blown film production lines, and commonly used 7-layer, 9-layer or even 11-layer film structures. Polyamide 6(PA6) has good barrier properties and mechanical strength, and is an ideal material for the production of blown film grade food packaging films. However, the high crystallization rate of polyamide 6 limits its processing window. Therefore, processors need to make concessions in terms of production efficiency or improve their processability by mixing polyamide 6 with special amorphous polyamides or polyamide copolymers, but this will greatly reduce the cost-effective advantages of such films.
Akulon developed by DSM®XS solves this problem. This cost-effective advanced technology effectively combines barrier properties, printability, heat sealing and impact resistance. Compared with traditional polyamide 6, Akulon®The crystallization rate of XS in the bubble is much slower, which provides processors with more operating space in terms of processing conditions, making it easier and more efficient to produce flexible food packaging films while retaining the unique barrier and mechanical properties of polyamide 6.
Akulon®XS not only has good mechanical strength, puncture resistance and barrier properties, but also can produce thinner and lighter films, bringing quality and cost advantages and reducing waste.
In addition, EVOH, which is a material having high barrier properties, is excellent in gas barrier properties, transparency, glossiness, mechanical strength, stretchability, abrasion resistance, cold resistance and surface strength. In food packaging, EVOH plastic containers can replace glass and metal containers. The EVOH high barrier resin brought by Kolali at the 2016 chinaplas exhibition can provide excellent gas barrier performance and chemical resistance, and can be used in multilayer structures.
Biological packaging and biodegradable packaging prospects
Consumers are paying more and more attention to environmental protection, and how to reduce the use of fossil products from the source has become a topic of concern to enterprises. Among them, bio-based packaging materials have become an important choice.
