The PRO-POUCH, a non-foil retort pouch, includes a dual purpose retort zipper designed for easy opening and secure closing. The pouch features transparent windows to allow consumers to see the product in the pouch. According to the company, the PRO-POUCH can hold wet and semi-wet pet food products.
The Prolamina-brand PRO-DURA polypropylene bags, on the other hand, hold dry pet food products. The bags now include an optional pinch bottom for billboard branding space. According to ProAmpac, this bottom prevents infestations better than traditionally sewn closures.
