Reported Todd in December, “With January increases of 2¢/lb, 3¢/lb and 5¢/lb, customers were wondering how the price would be implemented and at what level.” She also noted that Westlake, with the lower price hike, announced that it would issue another price increase for February. “As such, it appeared that the January price uptick will be limited to 2¢/lb, with a further increase of undetermined size in the cards for February. Some PVC converters think the January price hike would be pushed back and implemented in February.”

While the melting process does not provide perfect mixing, this study shows that mixing is indeed initiated during melting.

SACMI’s new line consists of four modules for feeding, scoring, folding and inspecting both tethered and traditional caps. While traditional caps have horizontal-cut tamper-evident bands, SACMI’s system can produce at least eight types of tethered caps with hinges or single or dual tether strips, some with ability to “lock” the cap away from the bottle neck for ease of drinking. All these types of caps could be molded either on SACMI’s popular continuous compression molding (CCM) machines or by injection molding.

Additive technology creates air pockets in film during orientation, cutting down on the amount of resin needed while boosting opacity, mechanical properties and recyclability.

Citing ACC results going into December, Greenberg reported that PP suppliers ran their reactor a bit higher in November, at about 80%. He noted that exports were a bit stronger, but representing only 6.6% of sales. “Domestic processors were turned off by the steep cost-push price increase last month (November) and slowed their purchases to only 96.5% of the trailing 12-month average,” Greenberg added. “Total production outstripped the weak sales and consequently, upstream inventories built for the second straight month back to levels not seen since April.”

Across the show, sustainability ruled in new materials technology, from polyolefins and engineering resins to biobased materials.

Polystyrene prices dropped another 3¢/lb in December, following a 4¢/lb drop the previous month, but flat prices for the January-February time frame were ventured by both PCW’s Barry and resin pricing expert Robin Chesshier. This scenario is primarily attributed to improved benzene supply due to plenty of Asian and European imports underway. Barry did add that while there was a likelihood of January benzene contracts dropping 10-20¢/gal, it would translate to only 1-2¢/lb for PS resins.

Prices of the five commodity resins were heading into 2024 at a lower point, but typical moves to reverse the overall downward trend of the fourth quarter were underway. This was particularly the case for PE and PVC, with suppliers issuing early first quarter price hikes. Such attempts are facing slowed domestic and global demand, higher supplier inventories and generally lower prices of key feedstocks. PET resin prices might differ just a bit if key raw materials move up.

Greenberg characterized spot PE prices as selling at deep discounts through December, and reported that transactional prices were well below levels reflecting the 9¢/lb increases reported by the major indices in 2023. Quoting November supply/demand results from the ACC (American Chemical Council), he reported, “PE production was almost identical to October, as reactors again ran just shy of 85% capacity and PE exports were above 2 billion pounds for the seventh straight month and comprised nearly 47% of total PE sales.”

The first module is the ORGRS (at left in the photo), described as sturdy and “extremely compact” waterfall feeder that orients and feeds the caps. Newly designed according to user feedback, it features faster maintenance and cleaning, thanks to easier internal access; many components can be disassembled without tools. It’s also said to run very quietly, due to soundproofing and low-noise compressed-air blowers. A deionizer is an available option.

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

Chesshier ventures that PE prices in January-February could either be flat but with potential for an increase, particularly if the exports market strengthens. Similarly, Barry saw potential for an increase, as he expected exports to pick up, but was not quite certain of domestic demand. He noted that processors had stocked up due to lower pricing at the end of 2023. These sources also point to the impact of new capacity, particularly from major new player Shell as well as NOVA Chemicals and Baystar, leading Barry to say, “2024 will see a “market share battle.”

Finally, the PFMC unit inspects the cut of the tamper-evident band and measures its breaking force. This unit performs destructive tests on selected cap samples. It can work as a standalone unit or integrated in a production line. It can also test traditional tamper-evident caps. This unit integrates a CVS CUT camera device to inspect the tamper-evident band before the destructive test, and it records quality statistics associated with individual spindles of the SFM module. Quick format changeovers allow testing of caps of different diameters. It also provides feedback control of cutting-tool temperature to counteract any drift in cutting performance.

Eventually it is expected to produce a range of octene copolymers, including film grades. Shell was restarting the ethane cracker at its Monaca, Pennsylvania, site on the evening of Dec. 25, according to a social media post, while Baystar was in the process of starting up a production unit at Pasadena, Texas, on the afternoon of Dec. 28, according to a flaring notification.

Processors with sustainability goals or mandates have a number of ways to reach their goals. Biopolymers are among them.

Polypropylene prices in December were flat, in step with propylene monomer; this despite that the anticipated recovery of monomer tightness had yet to occur due to two unplanned shutdowns, according to PCW’s Barry, Spartan Polymers’ Newell and The Plastic Exchange’s Greenberg. Said Newell, “As long as monomer inventories remain tight, there’s some volatility.” He notes that domestic PP demand ended badly in 2023, and he expected suppliers would likely have to further cut production rates from the low 80s percentile to the mid-70s for an improved supply-demand scenario.

Despite price increase nominations going into second quarter, it appeared there was potential for generally flat pricing with the exception of a major downward correction for PP.

PCW’s Barry, somewhat in contrast, ventured further price correction of PP and the monomer through January and February, noting that spot monomer prices were well below contract prices and that domestic PP resin tabs were still too high compared to global prices. Characterizing 2024 as a year of “market share battles,” he reports that with no anticipated near-term uptick in demand, some traders were positioning for PP prices to move lower in first quarter.

The Plastics Industry Association (PLASTICS) has released final figures for NPE2024: The Plastics Show (May 6-10; Orlando) that officially make it the largest ever NPE in several key metrics.

Chesshier noted there was no real cost push from any of the key feedstocks, including styrene monomer, ethylene and butadiene, with continued lackluster demand for PS resins. Reported Barry, “Supply remained ample amid a generally gloomy demand outlook. The implied styrene price based on a 70% benzene/30% ethylene spot formula was down 1¢/lb by end of December.
