About us


Big Pak — big bag and PE foil manufacturer from Ełk
Big Pak is a Polish manufacturing company established in 2009 in Ełk, specialising in FIBC flexible containers (big bags) and PE films. We employ around 130 people and serve customers in Poland and Europe - from bespoke project orders to framework contracts with the largest fertiliser manufacturers on the continent.
What we produce
Big Pak produces two types of industrial packaging:

FIBC Big Bag Sacks
flexible containers for transport and storage of bulk materials. We specialise in single-loop bags for the fertiliser and agrochemical industry, and four-loop bags for the construction, chemical, and food industries. We hold UN 13H3 approval for the transport of hazardous materials (ADR/RID/IMDG).
4 million
pieces per year
1 or 2
hooks
PE films
manufactured using 3-layer blown film technology: industrial films, layflat tubing, centerfold films, shrink films and liners for Big Bags. We are the only big-bag company in Poland that produces its own film — this eliminates the issue of dimensional mismatch between the liner and the bag.

Both segments are manufactured at a single plant in Ełk. The GRS v4.0 certificate enables the supply of products with a documented share of post-consumer recycled materials (rPP and rPE) — with documentation for ESG reporting and compliance processes.
From a workshop to a leading supplier in Poland
Big Pak was established in 2009 in Ełk on the initiative of Adam Koniuszewski.
The breakthrough came with the cooperation with Grupa Azoty and Anwil - the largest fertiliser producers in Poland. This entry into the fertiliser industry built the company's position and triggered further investments: the construction of its own production hall and company headquarters, and the expansion of its machinery fleet. The next step was our own PE film line - first one machine, then a second. Today, Big Pak is the only company in Poland producing big bags and PE films under one roof.
Currently, Big Pak is one of the leading suppliers of fertiliser bags in Poland - we supply to most fertiliser distributors in the country, and we have maintained our position as a leading supplier to Grupa Azoty and Anwil for many years.

Certificates and standards
Big Pak manufactures under a certified quality management system (ISO 9001:2015, TÜV NORD Polska). Big Bag sacks have UN 13H3 approval for the transport of dangerous goods (ADR/RID/IMDG, COBRO/Łukasiewicz certificates). The GRS v4.0 certificate (Global Recycled Standard, Control Union) enables production with a documented share of post-consumer recycled materials.
We were the first in Poland to obtain the GRS certificate in the big-bag segment - this opened the way to cooperation with clients who require ESG documentation and supply chain reporting.
Environmental responsibility
We produce packaging that goes back into circulation. The GRS v4.0 certificate confirms the share of post-consumer materials in our products — both rPP in bags and rPE in films. For customers, this means ready-made documentation for ESG reporting without additional audits on the buyer's side.
In the film production process, we use a closed cooling water loop — with zero discharge to the sewerage system.
