Food grade bags - are made with resins meeting FDA standards to be used for food purposes. Food grade bags are manufactured in a clean room facility and can be certified by a food safety standard like SQF, AIB and/or BRC. A food grade bag which has been manufactured by a facility that has been audited and is certified by a food safety standard like the American Institute of Baking(AIB), Safe Quality Foods(SQF), or British Retail Consortium(BRC) or others, is considered a certified food grad bag. Our bags are made of resin which meets the FDA food grade requirements.

UN rated bags are put through a series of rigorous tests such as, drop test, topple test, and top lift test. The testing is executed by an independent testing facility. Once the bag is UN certified, each bag will be assigned a specific UN number identifying that specific bag. The UN certification usually lasts for one year, or otherwise specified by the testing house, some will certify longer.

Multi-trip bags Most bags are designed with a 5:1 safety factor, meaning the bag is rated to hold 5 times the amount of the bags safe working load. A 5:1 is intended for single use bags. 6:1 bags are designed for multi-uses only.

Chemical bags used to transport chemicals.

Conductive or static dissipative bags (Anti-static) the difference in the two is the flow of the electrical resistance. Conductive bags allow the electrons to flow easily across the bag and charges go to the ground or another conductive object. Static dissipative bags allow the electrons to move slower and more controlled through the antistatic fabric, reducing the charge.

Valve bags or liquid bags allow liquid to be stored or transported easily. Valve bags are equipped with a valve port for releasing the liquids in a controlled manner.

Quality of Service

TechSun is committed to setting a high level of quality for customer satisfaction in every stage of manufacturing.

TECHSUN ’s QA/QC-HSE dept is ready to meet high level customer requirements. Quality is achieved by high level educated and experienced personnel. TechSun is committed to assisting employees in their pursuit of excellence by providing them with the leadership, cooperative environment, training and facilities.

Satisfying customer requirements is more than just designing a bag. Quality is inherent in every part of process in TechSun. From the choice of materials, to the use of advanced technology, to the maintenance of safety standards, and to the timely delivery of the finished goods- all are of equal importance in making a TechSun product.

Quality of system

We meet the strictest industry standards. At TechSun , we apply the strictest quality standards of any leader in the FIBC industry. Techsun , Meet and exceed the ISO 9001 requirements in every production process. High quality standards are applied to make sure that the system works properly and the final product meets the desired criteria. A quality assurance system insists on certain regulations for the achievement of this target. This support confirmed the manufacturing standards, accountability and documentation.

Quality of product

At TechSun , quality is an integral part of our mission and core business values. These guide our actions to ensure that we deliver the highest quality products to satisfy our customers’ requirements. The QA/QC-HSE dept use its own equipment and devices (properly calibrated) for measurement, tests and non destructive examinations.

Technical specifications of raw material, strength properties and UV content of components are all checked with respect to the international standards.

Quality control process in TECHSUN consists of three major steps:

• Material inspection and testing
• Process inspection and testing
• Final quality control

Throughout the material inspection process, yarn is tested for width and strength. Once yarn is woven, fabric is tested once again for width, fabric weight, weaving density in addition to the strength of the warp and weft. Samples taken out of fabric are also tested for UV resistance. The fabrics are tested for more than 200 hours. This process inspection also applies to the final quality control where the bags are measured and visually checked to ensure the customer’s specifications. Finally, the bag is tested in the test rig machine.

Test parameters

• Elongation test
• Breaking test
• UV resistance test
• Coating performance test
• Drop test
• Stacking test
• Fabric test
• Friction test
• Raw Material property test
• Melt Flow Index (MFI) test
• Ash Content test

TECHSUN is able to track back through the production process, all the way to the raw material, to identify the problem. Using the traceability of quality assurance system, all non-conforming products are marked in the plant using special means. The result of this stringent quality assurance program is the product that customers of UAC have come to trust and depend on.

• Demand for FIBC/Jumbo Bag is growing day by day. It is use for many different ways for storing and handling the products in bulk quantity. It handle and carry weight from 500 kg to 2000 kg as per needs. FIBC should use proper ways for storing and transportation of materials.
• Jumbo Bag Storing –it is best for storing materials in clean safe manner. It protects from sunlight and climatic changes.
• Jumbo Bag Filling – Bag is filled by resting it on ground or on a pallet as per packaging needs.
• Jumbo Bag Discharging – In common cases FIBC is discharge by help of gravity but in some cases it required suction for emptying. Special discharging sprout use for emptying the bag.
• Jumbo Bag Lifting – FIBC/Jumbo Bag are lifted through its loops placing on forks. It easily handle and move from one place to other by the help of loops.

• Form–Fitted Liner – Designed to take the exact shape of the FIBC. Form-Fit Liners will allow improved filling and complete discharging of product. Unlike a basic “tube liner”, Form-Fit Liners offer a flat top and bottom and incorporate a spout diameter and length to best compliment the FIBC’S fill and discharge spouts.
  
• Full Open Discharge – A type of discharge whose outlet extends from the bottom seam and follows the bag’s base dimensions. Also called a Full Open Dump.
  
• Hem/Hemming – A fold and sew, or glue operation, which prevents fraying of cut fabric and will add lift strength and seam strength to each bag. This also provides a clean finish to the FIBC. It may be either towards the inside or outside of the bag. Hemming can be used to achieve desired FIBC dimensions.

• Shelf-Life of FIBCs – As of this present date, the FIBCA is not aware of, nor has it ever been presented with any data, test reports, or studies determining the shelf life of an FIBC. Any recommendations in regards to the shelf life of an FIBC, are solely the responsibility of each company making such declarations. The Flexible Intermediate Bulk Container Association does not endorse any typical shelf life for a FIBC / Bulk Bag. Variables such as UV inhibitor used, construction (fabric weight, thread, webbing, etc.), exposure to environmental hazards (UV, temperature and humidity), storage methods, handling methods and the contents of the FIBC can dramatically impact the shelf life of a FIBC. The best method for determining if a FIBC remains suitable for use is to conduct periodic performance testing (top lift, UV, etc.) on samples and compare the results to the results from the newly manufactured samples from same lot. Samples should continue to meet industry standards such as those set forth in ISO 21898
  
• Sift-Resistant Construction – A type of an FIBC construction that provides resistance from product sifting when the bag is filled with very fine materials. Also referred to as “Sift ¬proof’ construction. This typically utilizes coated fabric and filler cord in the sew lines.
