Driven by consumption upgrading within health product, beverage and sauce industries, irregular pouches, stand-up doypacks and spout pouches gain wide application owing to attractive appearance, portability and easy-tear features. Such packaging styles become common options for end products. Many health supplement and beverage manufacturers encounter difficulties on equipment compatibility. General packaging machines are designed for only one standard pouch type, requiring long adjustment periods during product changeovers. Filling irregular pouches tends to bring positioning deviation, material leakage and wrinkled seals, which affect overall qualified rates directly.

To tackle production difficulties related to various pouch types, shaped pouch packing machines, doypack filling machines and spout pouch filling machines serve as essential units for flexible packaging lines. As a technology-oriented enterprise, Shanghai Rotypack Intelligent Equipment focuses on R&D and production of horizontal flexible packaging machinery. The RT and RP series pre-made pouch machines and dedicated models for internal straw pouches cover fully automatic filling and sealing procedures for irregular doypacks and spout-equipped stand-up pouches. The equipment suits small-volume production ranging from 25ml to 200ml for health supplements, functional drinks and pasty sauces.

The machines adopt Siemens servo control systems with positioning accuracy reaching ±0.1mm, enabling integrated stable operation for grabbing, opening and filling irregular pouches. The whole frame applies food-grade 304 stainless steel with modular structures, supporting quick conversion between irregular pouches, spout pouches and regular doypacks. Extensive mechanical disassembly is not required, effectively reducing time spent on format adjustment. Different from universal standard equipment available in the market, our company supplies customized modification solutions for small-batch irregular pouch projects. Multiple production lines for irregular spout pouches have been put into operation to realize mass production of easy-tear portable packages, matching differentiated competition requirements for fast-moving consumer goods on retail shelves.

Supported by an in-house standardized manufacturing plant covering 16,000 square meters and a professional R&D team, the company operates without intermediate traders. Clients can arrange on-site machine trials at our factory, and technical engineers provide on-site plant surveys to formulate pouch-matching layouts. As an original manufacturer participating in drafting two industrial group standards for packaging machinery, all finished machines follow strict 6S management procedures during production. Quality control rules follow stricter requirements compared with common industrial norms, meeting operational demands for domestic factories and overseas shipments with CE certification.

Differentiated packaging builds core competitiveness for food and health brands, making multi-functional irregular pouch filling equipment necessary upgrades for modern production lines.
