Vidrala saw glass sales decline by 6.7% in the first half of the year amid soft market conditions.
It reported sales of €750.1 million to the end of June this year, down 6.7% from last year first half sales of €813.4 million.
Profit was €216 million, down about 2% compared to the first six months of 2024.
However it predicted an increase in volumes by the end of the year.
CEO Rául Gómez Merino said while results were broadly in line with expectations, demand for the Spanish headquartered glassmaker remained soft in the first half of 2025.
"In fact, actually persistently weaker than initially expected," he said.
The company was boosted by its operations in Brazil which posted a 4% increase in volume, minus 1% in Iberia and minus 7% in the UK and Ireland.
The comparison basis in the UK and Ireland though was impacted by an increase in volumes in 2024 as a result of the impact of The Park beverages filling site in Bristol, UK.
Iñigo Mendieta de la Rica, Corporate Finance Director, said: "Our margins in the UK remain solid despite this weak top line performance. And that gives me the confidence that we can recover volumes and recover market share."
Mr de la Rica discussed the impact of the UK Extended Producer Responsibility scheme, where recycling costs will shift from local authorities to beverage producers.
The company had initially suggested it could be £240 per tonne, but the final fee was round £192 per tonne.
"The reality is that it is probably too early to assess potential impact on volumes, but we are not seeing any significant changes in customer behaviour.
"And in any case, it's relevant to understand that if this regulation means that the UK is less competitive, it should mean that other regions are more competitive.
"Vidrala is a group composed by three different regions, Iberia and others, the UK and Brazil.
"And finally, if we take a look at the very final impact, the impact on the price of the final product for a consumer, it should be no more than 2%, 3% of the selling price of a standard product.
"So while it is not good news, but probably not dramatic."
For the remainder of the year, the company forecast volume growth of up to 1%.
Mr de la Rica said: "The reality is that we are expecting more than a significant recovery on end demand. We're expecting a progressive contribution of volumes in the second half.
"Probably the third quarter will be key in that sense.
"But let's consider that for the full year, we are expecting to be slightly positive in terms of volumes, okay, something between 0% to plus 1%."
