NEX-BAG
Industrial Bag Films

For the chemical, pharmaceutical, wood, and furniture industries

  • FFS bags up to 50 kg
  • Tubular films, gusseted tubular films, semi-tubular films, tapes
  • Mono, 3- and 5-layer lines

We solve specific packaging problems

NEX-BAG is a product group for forming industrial bags and hoods. From pharmaceuticals, through chemicals and wood pellets, to big bags – our films offer durability that guarantees safe packaging, transport, and long-term storage of heavy and bulk loads.

Bag breakage on the FFS line

NEX-BAG Solution: NEX-BAG FFS HQ – a multi-layer construction with mLLDPE and enhanced tear and puncture resistance, selected based on line speed and product characteristics (granules, powder, pellets). Stable tubular film geometry eliminating stretching and insufficient sealing in the weld area.

Value for You: Fewer defects on the line, higher OEE, reduced raw material losses, and fewer complaints from the end customer.

Purity requirements for pharmaceutical products

NEX-BAG Solution: NEX-BAG FARM – an application dedicated to the pharma industry, produced under controlled conditions with raw materials meeting pharmaceutical requirements. Capability to operate in a GMP-friendly regime and full quality documentation per batch.

Value for You: Compliance with pharma industry requirements, auditability, and full traceability of deliveries – without risk to client compliance.

Need for packaging heavy loads (15–50 kg)

NEX-BAG Solution: NEX-BAG BB – dedicated film for big bags and FFS bags with loads up to 50 kg. High tear, puncture, and drop resistance, resistance to long-term outdoor storage (UV, temperature fluctuations).

Value for You: Safe packaging of heavy bulk loads, lower losses in transport and warehouse, reduction of “spilled bag” type complaints.

ESG, PPWR requirements and implementation of PCR/ISCC PLUS

  • NEX-BAG Solution: Variants with PCR (post-consumer recycled) content for non-food applications and ISCC PLUS (mass balance) for applications requiring contact with food/feed raw materials, in a mono-PE Design for Recycling construction. Implementation without the need to replace the client’s FFS line.

    Value for You: Achievement of ESG goals and PPWR requirements without CAPEX, simpler recycling path at the end of the packaging’s life cycle.

Bag as a brand carrier – printing and branding

NEX-BAG Solution: Integration with NEX PRINT (flexo CI, up to 10 colors) directly on film for FFS, big bags, and industrial bags. Print design optimized for bag geometry and seals, maintaining readability under EAN, QR codes, and GHS pictograms for chemicals.

Value for You: The bag as a brand carrier in the B2B chain and at the end customer’s site, compliance with chemical and logistical labeling requirements.

Most Frequent Technical Questions

What is the maximum load weight for a NEX-BAG FFS bag?

The market standard is 50 kg – this limit results from EU OHS requirements (above this, two people must carry it; up to 25 kg, one person). Technologically, our bags, especially in the FFS HQ and BB variants, can withstand much more and are capable of operating under conditions of a 2–3 meter drop without breaking. We determine the parameters for each specific client application.

Does NEX-BAG FARM meet GMP requirements?

Yes – we produce NEX-BAG FARM for pharmaceutical applications in a controlled production regime (including protective clothing, caps, dedicated procedures), with full quality documentation per batch. Our portfolio includes implementations for applications such as eye drops and other products requiring the highest purity.

What is the difference between NEX-BAG FFS ST and FFS HQ?

HQ is a downgauging path: the same bag can be made thinner with maintained or improved strength, thanks to a different raw material regime (including mLLDPE and more advanced layered constructions). HQ is chosen by clients who drop bags from greater heights, transport over long distances, or consciously want to reduce film consumption per bag.

Are NEX-BAG versions with printing available?

Yes – flexo CI printing up to 10 colors integrated with NEX PRINT, using water-based or solvent-based technology. Standard in-line prints are usually simple (up to approx. 6 colors), but technologically we support the full 10 colors along with EAN, QR codes, and GHS pictograms for chemicals.

How does a 5-layer construction differ from a standard 3-layer construction in FFS bags?

A 5-layer construction is a market rarity for industrial bags – it allows for selective design of properties in individual layers: one for mechanical strength, another for slip/machinability, another for PCR content or mLLDPE. The effect: higher strength at lower thickness, which translates into real material savings.

Can NEX-BAG bags replace paper bags with a film coating?

Yes – our mono-PE bags are a full-fledged alternative to hybrid bags (paper + film coating, so-called “pseudo-recyclable”). We implement them, among others, in cement plants, construction chemicals, sugar factories, and feed production. The main difference: real recyclability of the PE stream and full compliance with PPWR / Design for Recycling.

What sustainable variants are available for NEX-BAG?

We offer PCR and PIR for non-food applications up to 55%, ISCC PLUS (mass balance) for food/feed/pharma applications, downgauging, and mono-PE constructions compliant with Design for Recycling. Implementation does not require changing the client’s FFS line – we work within the existing packaging process.
