Overview of BIS Certificate For Polypropylene Sacks

BIS Certificate for polypropylene sacks is crucial for the safety and usage of the same. Polypropylene sacks, commonly known as PP woven sacks or woven polypropylene bags, are strong and durable bags made from woven polypropylene fabric. This fabric is produced by weaving together strands of polypropylene resin, creating a tear-resistant material ideal for packaging and storing a wide range of products. Polypropylene sacks, being resistant to water, strong, and durable, are simply indispensable in packaging, particularly in cement production. 

To meet such critical demands, Polypropylene (PP) Woven, Laminated, Block Bottom Valve Sacks, which are designed specifically to be used for the packaging of 50 kg cement. This is as per Indian Standard IS 16709:2017 and provides national standards of safety and performance to the sacks. These PP sacks are woven to withstand the harshness of cement bagging with greater strength, water resistance, and piling resistance. Manufacturing BIS Certificate for polypropylene sacks guarantees end users and stakeholders that the utilized sacks are not just reliable but superior in quality as well.

IS 16709:2017 Textiles Polypropylene (PP) Woven, Laminated, Block Bottom Valve Sacks for Packaging of 50 Kg Cement

This Indian Standard IS 16709:2017 defines the technical and performance requirements of block bottom valve design laminated woven polypropylene sacks as economic packets for cement packing and storage in a safe manner. The sacks are made of laminated woven polypropylene fabric to have a proper barrier against moisture. The bottom block configuration offers support for sacks to be held in shape, which is best for piling and storage with less collapse or tipping. The configuration also enhances the management features of the sack for convenient handling in the cement supply chain. IS 16709:2017 defines some of the key parameters, which are given below: 

• Sack weight and capacity
• Tensile and bursting properties
• Valve opening and build-up
• Lamination integrity
• Sampling procedures and test methods

These specifications are subjected to strict tests to make sure that sacks can endure the everyday stress factors like the weight of loads, transit shocks, and abrupt weather changes, more precisely, moisture, which can become a key factor in determining the quality of cement.

Procedure to Obtain BIS Certificate for Polypropylene Sacks

Procedure to obtain BIS Certificate for polypropylene sacks is given below: 

Application Submission

Submission of the application is the second step but the first step is to prepare the application correctly. Hence one must be aware about the following four steps given below: 

• Submission of application form (Form VI of the Product Certification Scheme)
• Upload supporting documents
• Payment of the application fee and processing fee
• Upon receipt of the application, the BIS officers check for completeness and accuracy.

BIS Audit by the Officers 

Upon the acceptance of the application, the factory auditing team of BIS carries out the factory audit. At the time of auditing, the BIS inspection team visits the production unit to:

• Verify the manufacturing process and capacity.
• Verify the availability and working condition of the test equipment.
• Inspect the quality control system of the factory.
• Keep a record of in-process inspection and raw material storage.
• Random testing of products

The firm must have an in-house laboratory as per BIS standards and is to follow Standard Operating Procedures (SOPs) as mentioned in the submitted quality manual.

Testing Samples

Audit samples are tested as per IS 16709:2017 standards in BIS-approved laboratories. They consist of the following tests:

• Breaking strength
• Bursting strength
• Water resistance
• Dimensions and tolerances
• Valve quality and integrity of lamination

Those products that successfully go through all the mandatory tests are said to be fit for certification. Where any test is not passed, the faults can be requested from the manufacturer to rectify and reapply.

Grant of BIS Certificate for Polypropylene Sacks

After sample clearance and a satisfactory audit report, BIS grants the license to the manufacturer. The license permits the utilization of the ISI mark on approved PP woven sacks. It is valid for a specified period and needs to be renewed periodically. The manufacturer's periodic surveillance also needs to be conducted, i.e., surprise factory inspections and market sample tests for continuous compliance.

Documents Required for the BIS Certificate for Polypropylene Sacks 

The documents to be submitted and prepared in order to get a BIS Certificate for polypropylene sacks must be in hand with the manufacturer before initiating the process of applying. The list of such documentations is given below:

• Duly filled BIS Application Form (Form VI)
• Copy of Company Registration Certificate (e.g., GST, Udyam, ROC)
• Authorized Signatory’s ID proof and photograph
• Authorization letter (if applicable)
• Product technical specifications and datasheet
• Product samples for lab testing
• Test report from BIS-recognized laboratory (not older than 90 days)
• Manufacturing process flowchart
• Details of production and testing equipment
• Factory license or related approval
• Copy of Trademark Registration Certificate (if applicable)
• Brand Authorization Letter (if brand owner is different)
• Declaration of conformity to relevant Indian Standards
• Affidavit/Undertaking for adherence to BIS terms
• For foreign manufacturers: Authorized Indian Representative (AIR) details and agreement

Timeframe for BIS Certificate for Polypropylene Sacks

Duration for BIS Certificate for polypropylene sacks varies based on whether the manufacturer is Indian or foreign.

• Indian Manufacturers: The Typical duration is around 30 days, provided the paperwork is perfect and the sample inspection gets cleared on the first attempt.
• Foreign Manufacturers: Almost 180 days are required to certify, as there are certain extra steps involved, like the delegation of foreign inspection, third-party coordination, and transit.
