When preparing for long-distance treks, mountaineering excursions, or wilderness expeditions, calculating gear weight is a science. A fundamental question asked by both retail outdoor enthusiasts and commercial suppliers is: "How much should a hiking backpack weigh?"
According to classic outdoor industry guidelines, a fully loaded trail pack should not exceed 20% of your total body weight for multiday hikes, and 10% of your body weight for single daypacks. For example, a hiker weighing 150 lbs (68 kg) should target a maximum pack weight of 30 lbs (13.6 kg). This threshold represents the "maximum load limit" before performance degrades, musculoskeletal fatigue sets in, and the risk of injury rises.
Outdoor suppliers and brands face a constant challenge: how to minimize the "dead weight" of gear. This includes the weight of the water bladders, food pouches, and preservation films carried in the backpack. Dongfa Printing Co., Ltd. serves this macro trend by producing high-barrier, ultralight composite films and spout pouches that help outdoor supply brands minimize consumable pack weight without sacrificing durability.
Our ultralight composite structures (75μm to 136μm thickness) replace heavy glass, metal, and thick rigid plastic. This directly cuts down the consumable weight carried in the backpack, allowing hikers to maintain the optimal under-20% body weight ratio.
Utilizing high-performance BOPP, VMPET, and PE, our packaging protects freeze-dried food, trail mixes, and energy bars from humidity and contamination, maintaining nutritional integrity under harsh, high-altitude trail conditions.
Designed for multi-day hiking meals. Our specialized retort packaging films withstand high-temperature steam sterilization (121°C), providing shelf-stable, preservative-free ready-to-eat meals ideal for outdoor activities.

A: A fully loaded hiking backpack should not exceed 20% of your total body weight. If you weigh 70 kg, your pack should weigh 14 kg or less. This includes the pack, gear, food, and water. Minimizing packaging weight is critical to staying under this limit.
A: Rigid containers (cans, glass jars, thick plastic bottles) have high tare weights. High-durability flexible packaging, such as Dongfa's spout pouches and aluminum composite films (ranging from 75μm to 136μm), offers the same or superior protection at a fraction of the weight, lowering a hiker's base load.
A: Yes. Our retort packaging films are specifically engineered to withstand sterilization temperatures of 121°C and can resist low-temperature storage. This is ideal for freeze-dried trail foods and hydration packs used in extreme alpine conditions.
A: Absolutely. All materials, including BOPP, VMPET, and PE, are strictly sourced, and produced in our GMP-compliant cleanroom facility. They undergo rigorous testing to ensure they are 100% safe, odorless, and chemically inert for food and medical packaging.
A: We provide complete customization, including material combinations, customized bag shapes, specific spout sizes (e.g., 8.6mm spouts), variable thicknesses (75μm - 136μm), surface effects like matte or glossy UV ink printing, and customized roll films for automatic filling lines.
