QUALITY CONTROL

TRL is a leading producer of high-tech flexible packaging materials.

The quality of our products is appreciated in India and beyond

Our success is underpinned by state-of-the-art technologies developed and introduced by a highly qualified and experienced team of professionals.

The enhancement of technical processes and the application of new advanced materials allow our company to provide customers with flexible packaging which is both competitive and advanced.

Our plant’s complete process flow ensures the continued quality of our products: starting with design development through to slitting and packing, together with continuous monitoring of processes at every stage.

THICKNESS

FLIM THICKNESS

Film thickness affects properties such as transparency, strength and elasticity. As a rule, when thickness increases, strength also increases but transparency and elasticity are compromised.

Monitoring variations in film thickness prevents reels from overstraining and overstretching parts of the film. A mechanical micrometre is used to measure the thickness.

WEIGHT

SPECIFIC WEIGHT

The specific weight of a film (or weight per square metre) dictates material consumption as well as the production of labels, packaging and other materials. Specific weight depends on material density, coatings and also film thickness.

ELASTICITY

STRENGTH

The strength and elasticity of film materials determine the strong performance of the end product. Having tested our films for tensile strength and breaking elongation, TRL ensures compliance with requirements on strength characteristics in accordance with GOST 14236 and ASTM 882 standards. These measurements are made with the multipurpose UTM.

SEALING

SEALING ABILITY

Sealing is one of the main methods for bonding thermoplastics and this is precisely why sealability is a crucial feature of our packaging materials. In our laboratory, we test films with the HSG-C sealing machine. Each material is exposed to this check under specific temperature, time and pressure conditions. The strength of welded seals is measured in a similar fashion to tensile strength according to the GOST 14236 and ASTM 882 standards.

STATIC FROCTION

FRICTION

The static friction coefficient is a key parameter, determining the efficiency of film conversion on high-speed lines and its wider performance characteristics. We evaluate the friction coefficient against the GOST 11629 standard using an FP-2250 testing machine equipped with a smooth horizontal table and a moveable carriage.

WETTABILITY

WETTABILITY

The ability of the film to maintain contact with liquids and colloidal systems are central to the behaviour of the material. If wetting is good the liquid spreads evenly across the surface of the film but, if not, water droplets will ball together. Film wetting tension is measured according to ASTM D 2578-09 and helps to assess the suitability of the film to different printing methods.
