Series 4

Cylindrical polyethylene bottles with soft shoulders. For the 500 ml capacity, neck options include DIN 24/410, DIN 28/410, BPF 28/410, and a wide, non-standard neck for a 801 cap with a tamper-evident ring. For the 1000 ml capacity, DIN 28/410, BPF 28/410, and a wide, non-standard neck are available. Customers can choose any color for the product and its accessories.

The classic, convenient shape and variety of closures make Series 4 popular for a wide variety of products: from laundry gels and bleaches to veterinary medications and fertilizers. Neck types allow for a customized closure—a narrow dispenser for liquid soap, a wide neck for bulk products. A cap with a tamper-evident ring is typically used when a guarantee of factory sealing and tamper-evident protection are important until the moment of purchase. The soft shoulder line makes the bottle easy to pour, and the cylindrical body remains stable even when partially filled. Circular horizontal grooves provide a dedicated labeling area.
