Engineered for extreme performance, barrier isolation, and minimized unit weight on long-haul expeditions.
For outdoor gear designers, B2B procurement heads, and trail food companies, understanding how much a backpacking pack weighs is not just a matter of recreational comfort—it is a critical engineering challenge. In modern outdoor sports logistics, a backpack's total cargo weight consists of three core domains: the Base Weight (the dry pack itself, tent, sleeping system, and hardware), the Variable Load (fuel, food, liquids), and the Packaging Mass.
An average modern ultralight backpack base weight ranges from 10 to 15 pounds (4.5 to 6.8 kg), while standard traditional configurations weigh between 20 to 30 pounds (9 to 13.6 kg). In the B2B outdoor space, high-barrier flexible materials are playing an increasingly critical role. By substituting rigid metal cans, glass jars, and heavy molded plastic bottles with ultralight, high-durability multi-layer laminated pouches, manufacturers can reduce packaging weight by up to 85%. This weight savings directly improves base load margins for tactical, survivalist, and commercial backpacking systems.
For instance, replacing a standard 300g tin can of ready-to-eat trail meals with a 12-gram high-temperature retort pouch reduces shipping overheads, simplifies disposal, and allows a hiker to maximize caloric payload per unit of volume.

We consistently use high-quality materials for professional production and strict quality control.
Why global outdoor supply brands choose Dongfa Printing for custom flexible laminate production.
Utilizing high-barrier PET/AL/PE, PET/VMPET/PE, and specialized retort-grade cast polypropylene (CPP) polymers to achieve minimal physical thickness with maximum puncture resistance.
Through robust domestic supply chains in China, we offer wholesale volume pricing that minimizes margins on high-capacity output lines, lowering total packaging costs for brands.
Our printing presses operate within state-of-the-art GMP workshops, featuring integrated online optical inspection equipment to instantly detect micro-defects or material inconsistencies.
Tailoring lightweight flexible barriers to survive extreme environments and optimize global logistics pipelines.
At high altitudes, air pressure changes put tremendous stress on sealed containers. Traditional rigid plastics or low-grade plastics will easily pop, bloat, or leak. Dongfa's custom dual-layer and multi-layer structural films (e.g., 92μm PET+AL+PE and 115μm high-strength spouted options) offer high tensile elasticity and hermetic seal strength. This guarantees that your trail liquid rations, freeze-dried food, and electrolyte pastes maintain pristine barrier isolation at extreme altitudes and sub-zero temperatures.
Outdoor hikers require shelf-stable food systems that are ready-to-eat. Our retort-capable spout bags and flat-bottom pouches can handle the punishing thermal pressures of pasteurization and high-pressure steam cooking retort cycles (up to 121°C or 135°C depending on application). This allows pre-cooked trail foods to remain shelf-stable for months without the need for preservatives, minimizing pack base weights drastically.
Weight reduction is not just about the hike in; it is about the hike out. Lightweight flat-bottom pouches and liquid pouches can be easily compressed and rolled up after use. This space-saving design is critical for multi-day expeditions, allowing hikers to pack out empty trash with zero physical bulk.
Whether you are a premium food brand in North America or a performance liquid nutrition manufacturer in Europe, our flexible packaging roll films and pouches meet strict international certifications. We enable brands to achieve compliance with high barrier standards while optimizing freight container weight layouts, boosting logistics and shipping margins.
