Adsyl 5 C 30 F Terpolymer PP for Low-Temperature Sealing in Coextruded Films

In coextruded food packaging films, the seal layer often sets the practical limit on line speed and package appearance. A seal initiation temperature above 120°C can narrow the heat-seal window and increase the risk of shrinkage or wrinkling near the seal. In our work with film processors across Asia, we see growing demand for a sealant resin that combines low-temperature sealing with low haze and stable metallization. Adsyl 5 C 30 F is a terpolymer PP from LyondellBasell designed for this balance. Its 105°C seal initiation and 0.6% haze at 50 μm make it a practical option for food packaging film, metallized layers, and shrink film structures.

Tensile strength and impact strength are not listed in the public TDS for this grade. Because Adsyl 5 C 30 F is primarily evaluated by film seal and optical performance, we recommend requesting a current COA or additional technical documentation if molded mechanical data is required for your qualification process.

Key Properties

Low seal initiation temperature: At 105°C, the resin can form a seal at lower heat-seal jaw temperatures than conventional PP sealants. This can help reduce film shrinkage near the seal and broaden the operating window on high-speed packaging lines.
Good optical performance: 0.6% haze and 88% gloss at 50 μm support clear food packaging and shelf-facing film where product visibility matters.
Terpolymer structure: The propylene-ethylene-butene terpolymer backbone provides a wider seal window and useful hot-tack behavior for automatic packaging equipment.
Metallization suitability: The resin is designed for use as a metallized layer in coextruded films. Its film surface quality supports uniform aluminum deposition in barrier film structures.
No slip or anti-block additives: The grade is supplied as a bare-foot resin, allowing converters to adjust slip and anti-block levels independently for their own film structure and equipment.

Applications

A food packaging manufacturer switched to Adsyl 5 C 30 F terpolymer PP for the inner seal layer of a snack film structure. By lowering the heat-seal jaw temperature, the line reduced seal-area shrinkage while maintaining seal integrity.

A film processor used this grade in a double-bubble shrink film structure for meat and prepared-food packaging. The seal layer provided consistent seals and good transparency after orientation.

A converter selected the grade for a metallized BOPP barrier film. The metallized layer showed uniform appearance and maintained the barrier performance expected in dry food packaging.

A stationery film producer used the resin as a coextruded seal layer for folder and book-cover film. The low seal initiation temperature helped maintain film flatness during converting.

Technical Comparison

The table below compares typical public TDS values with common industry ranges for standard PP sealant resins. These ranges are for general reference only and do not refer to any specific supplier.

Property	Adsyl 5 C 30 F	Common PP Sealant Range
Seal initiation temperature	105°C	Above 125°C
Haze (50 μm)	0.6%	1.5%–2.0%
Gloss (45°)	88%	75%–80%
Melting temperature	132°C	160°C–165°C

Actual film performance depends on coextrusion structure, layer thickness, processing temperature, and additives. We recommend running a trial on your own line before full-scale adoption.
