The most common mistake in packaging procurement is evaluating format options based on unit price alone. It is an understandable shortcut—unit price is visible on every invoice—but it consistently leads to higher total costs. Here is the reality: a retort pouch may cost $0.17–$0.19 per unit versus $0.13–$0.15 for an equivalent metal can. At face value, the can appears 15–30% cheaper. But this comparison ignores six to seven additional cost categories that the can format systematically loses in. Read More

Реторт-пакет настолько хорош, насколько хороша его ламинатная структура. Комбинация слоёв определяет не только то, выдержит ли упаковка процесс ретортирования, — она определяет срок хранения, качество продукта, удобство для потребителя и соответствие нормативным требованиям. Read More

When food manufacturers evaluate packaging options, the instinct is often to compare the per-unit cost of retort pouches against metal cans. This is the wrong starting point. A retort pouch may cost 15-30% more per unit than an equivalent metal can. But once you account for the full supply chain—from empty packaging logistics through to retail shelf—the picture changes dramatically. Read More

The food packaging industry is experiencing a fundamental shift. According to Grand View Research, the global retort pouch market is growing at 7.0% CAGR (2024-2033), significantly outpacing the overall food packaging market growth of 4.1%. This reflects deliberate decisions by food manufacturers reassessing their packaging strategies. Read More

A retort pouch is a flexible packaging container constructed from multiple laminated layers of plastic and metal foil, engineered to survive high-temperature thermal sterilization—a process called "retorting." Unlike conventional flexible packaging that would fail under heat, retort pouches maintain structural integrity, seal strength, and barrier properties at temperatures between 121°C and 135°C (250°F–275°F).

Ordering custom flat bottom bags may seem complex, especially if you're doing it for the first time. However, breaking it down into clear steps makes the process manageable and ensures you get exactly what you need. Read More

MOQ (Minimum Order Quantity) is the smallest number of units a manufacturer will produce in a single order. For custom flat bottom bags, MOQ typically ranges from 5,000 to 50,000 pieces, depending on your specifications. Understanding MOQ is essential for budgeting and inventory planning. Unlike retail products where you can order single units, manufacturing custom packaging involves significant setup costs that must be spread across a minimum number of units to remain economically viable.
