Reliance PP Repol H034SG

Reliance Repol H034SG is a polypropylene homopolymer BOPP film grade developed by Reliance Industries Limited for high-speed biaxially oriented polypropylene film production. Officially recommended for oriented film processes, this grade is especially suited for low-thickness films and is widely positioned for adhesive tapes, food packaging, cigarette and textile overwraps, synthetic paper, and plain or metallisable BOPP films. For processors looking for a reliable PP homopolymer for high-output BOPP lines, H034SG offers a balanced combination of flow, stiffness, orientation behaviour, and line productivity.

Reliance Industries is one of India’s largest polymer manufacturers, and the Repol PP portfolio includes specialised grades for film, raffia, fibre, and injection moulding applications. Within this portfolio, H034SG is a dedicated BOPP film homopolymer rather than a general-purpose extrusion grade. That matters because BOPP film lines demand a resin with stable processing behaviour, good orientation response, and the ability to support thin-gauge film production at commercial line speeds. For buyers searching for Reliance Repol H034SG supplier in India, BOPP film PP granules, or 3.4 MFI polypropylene homopolymer for adhesive tape and packaging films, this grade is a strong fit for technically demanding film conversion environments.

Deep Technical Insights

The key technical parameter for Repol H034SG is its melt flow rate of 3.4 g/10 min at 230 °C/2.16 kg as per ASTM D1238. This MFR range is well suited to BOPP film extrusion because it supports a useful balance between melt strength and processability. In practical terms, that helps film producers maintain stable extrusion, controlled orientation, and consistent performance on high-speed lines, especially when targeting low-thickness films.

Typical property data associated with H034SG further supports its positioning as a BOPP film grade. The material is reported with density around 0.90 g/cc and Shore D hardness around 69 to 70, which aligns with the stiffness and surface durability expected in film applications such as tape base films and synthetic paper. Mechanical values commonly referenced for this grade include tensile strength at yield around 36 MPa, elongation at yield around 12%, flexural modulus around 1350 to 1400 MPa, and notched Izod impact around 40 J/m. Thermal performance is also relevant, with heat deflection temperature reported around 104 to 105 °C. These figures are typical values and should be treated as reference data rather than guaranteed specifications.

For BOPP processors, the processing window is equally important. Public technical references indicate extrusion temperatures in  the range of 220 to 260 °C, chill roll temperatures around 20 to 50 °C, MD stretching temperatures around 120 to 160 °C, and TD stretching temperatures around 150 to 170 °C, with typical stretch ratios of 4 to 8 in MD and 7 to 10 in TD. These ranges help explain why H034SG is preferred for high-speed oriented film lines, but actual settings should always be optimised based on line design, film structure, and target thickness.

Applications and Industry Use Cases

Plain and Metallisable BOPP Films

Reliance Repol H034SG is primarily designed for plain and metallisable BOPP film production where stable orientation, consistent thickness control, and good downstream converting behaviour are essential. In these applications, the grade supports film structures used across packaging, lamination, and speciality film markets. Its balanced flow and stiffness profile make it suitable for processors aiming to run thin films at commercial speeds without compromising film integrity.

Adhesive Tape Base Films

One of the most important application areas for H034SG is adhesive tape film. BOPP tape manufacturers need a polypropylene homopolymer that can deliver dimensional stability, surface consistency, and reliable orientation during film production. The stiffness and hardness profile of H034SG make it well aligned with tape base film requirements, where clean winding, stable film handling, and dependable converting performance matter.

Food Packaging and Overwrap Films

H034SG is also relevant for food packaging films and overwrap applications such as confectionery, bakery, cigarette, and textile overwraps. In these segments, BOPP film producers value a grade that can support high-speed processing along with good film appearance and regulatory suitability. Public compliance references for food-contact-related standards further strengthen the grade’s relevance for packaging structures, subject to full application and structure validation.

Synthetic Paper and Speciality Film Uses

Synthetic paper and related speciality film applications require a resin that can support stiffness, dimensional stability, and controlled orientation behaviour. H034SG fits well in this space because its property profile is aligned with film applications where printability, handling, and structural consistency are important. It is also useful in metallisable film structures where uniformity and downstream surface performance are commercially significant.

Comparable Alternatives

Within the Indian BOPP film market, the closest comparable grades to Repol H034SG include IOCL F1030FG or F1030FG1 and MRPL F03RR or F03RR1. These grades are commonly mapped in comparison charts as BOPP film homopolymers for food packaging, lamination, metallisable films, and related applications. IOCL F1030FG is especially relevant as a practical alternative because its melt flow range is close to H034SG and it is positioned for a similar BOPP film processing window.

The rationale behind choosing H034SG comes from its combination of verified BOPP-specific positioning, 3.4 MFR, suitability for low-thickness films, and acceptance across adhesive tape, packaging, overwrap, and synthetic paper applications. Compared with broader PP film grades, H034SG is more specifically aligned to oriented film lines rather than general cast film or extrusion use. Final substitution between H034SG and other Indian BOPP grades should always be validated through TDS review and plant trials, especially where film thickness, line speed, metallisation behaviour, or downstream converting performance are critical.
