When it comes to packaging food, especially for on-the-go snack pack meals or long-term storage, choosing the right material matters. Two popular options — sandwich wrapping paper and Mylar bags — are often considered for packaging sandwiches, snacks, or survival food. Each has unique properties, advantages, and limitations. This article compares these two packaging choices to help you decide which works best for your needs.
What Is Sandwich Wrapping Paper?
Sandwich wrapping paper, sometimes called deli paper or butcher paper, is a flexible, lightweight sheet used for wrapping food items. It is made from natural fibers and often coated with a light wax or plastic to offer some resistance to moisture.
This type of wrapping is widely used in delis, cafes, and households because it’s inexpensive, easy to use, and comes in various sizes. Many people like it for wrapping sandwiches, burgers, pastries, and cheese. It provides a simple way to keep food together and offers basic protection against dust and light handling.
Understanding Mylar Bags
Mylar bags are made from a polyester film that is metallized to enhance strength and barrier performance. They originated from the DuPont brand name “Mylar,” and are widely used for packaging food, electronics, and sensitive materials.
Unlike sandwich paper, Mylar bags create a stronger seal and offer superior barrier protection against moisture, air, oxygen, and light. They are commonly used in long-term food storage, emergency kits, camping provisions, and space-sensitive supplies. Mylar bags are typically used alongside oxygen absorbers to significantly extend the shelf life of dry goods.
Barrier Protection: Moisture, Air, and Light
One of the most important factors in packaging is barrier protection — how well the material keeps out unwanted elements.
Sandwich wrapping paper offers minimal barrier protection. The light coating can keep a sandwich from quickly drying out or picking up odors in the fridge, but it won’t stop significant air or moisture transfer. It’s suitable for short-term use — a few hours or a day — but not ideal if food needs to stay fresh longer.
Mylar bags, on the other hand, excel in this area. The metallized film blocks light and dramatically reduces air and moisture penetration. When properly sealed, Mylar bags extend the freshness of dry goods — such as rice, beans, dehydrated fruits, or jerky — for months or even years. For hot food like a sandwich, Mylar isn’t breathable, so condensation can build up inside unless cooled and dried beforehand.
Winner: Mylar bags for barrier protection; sandwich paper is fine for short-term freshness.
Convenience and Ease of Use
For everyday convenience, packaging should be quick and hassle-free.
Sandwich wrapping paper is straightforward: wrap, fold, and go. No tools are needed. It’s easy to reuse and doesn’t require special storage conditions. You can quickly wrap sandwiches in a kitchen or at a picnic with minimal effort. The tactile feel of wrapped food also has aesthetic appeal — think classic deli sandwiches.
Mylar bags require more effort. They usually need a heat sealer or a reliable iron to create an airtight closure. For long-term storage or emergency preparedness, this extra step is worth the effort, but for daily sandwich packing, it may be inconvenient. Additionally, once opened, a Mylar bag may not reseal well without a zip closure or sealing system.
Winner: Sandwich wrapping paper for everyday convenience.
Environmental Impact and Sustainability
Sustainability is increasingly part of packaging decisions. Both materials have environmental trade-offs.
Sandwich paper, especially uncoated or wax-free varieties, can be compostable or recyclable depending on local facilities. Paper breaks down faster in the environment and is less harmful if it ends up in landfill.
Mylar bags are more challenging to recycle due to the combination of metal and plastic layers. They are durable, but their longevity means they persist in the environment if not properly disposed of or recycled through specialized programs. Some brands offer recyclable Mylar, but availability is limited.
Winner: Sandwich wrapping paper for lower environmental impact.
Cost Considerations
Cost is a practical factor for individuals and businesses alike.
Sandwich wrapping paper is inexpensive and often sold in bulk for restaurants, delis, or families. It’s a cost-effective choice for daily sandwich packaging.
Mylar bags are more expensive, especially higher-quality, thicker bags designed for long-term storage. The cost increases further if you invest in a heat sealer or oxygen absorbers. For occasional use, it’s manageable, but for everyday sandwich wrapping, Mylar is less economical.
Winner: Sandwich wrapping paper for affordability.
Food Safety and Hygiene
Both packaging types can maintain hygiene, but in different ways.
Sandwich wrapping paper protects from direct contact with unclean surfaces and helps prevent contamination from handling. However, since it’s not airtight, it doesn’t protect food from airborne contaminants for long periods.
Mylar bags can be fully sealed, keeping food safe from contaminants, pests, and humidity. They’re superior when food safety over long storage is the goal. For perishable foods, however, the lack of breathability could lead to moisture buildup unless properly cooled first.
Winner: Mylar bags for long-term hygiene and safety.
Choosing What’s Best for You
Ultimately, the best packaging depends on your needs:
For daily sandwiches and short-term meals: Sandwich wrapping paper is convenient, affordable, and environmentally better for single-day use.
For long-term storage or emergency food supplies: Mylar bags offer unbeatable protection against air, light, and moisture.
For travel or camping: Consider combining both — wrap the sandwich in paper for handling and place it inside a Mylar bag for added protection.
Conclusion
Both sandwich wrapping paper and Mylar bags have their place in food packaging. Sandwich paper shines in convenience, cost, and sustainability, making it ideal for everyday use. Mylar bags, despite being less convenient and more expensive, provide strong protective qualities essential for long-term storage or harsh conditions.
By understanding the strengths and limitations of each, you can choose the packaging that matches your lifestyle and food storage needs. Whether it’s a quick lunch or emergency food stash, the right wrap makes all the difference.
