As a common food in daily diet, the material selection of the packaging bag for toast bread is crucial. Suitable materials not only protect the freshness and taste of bread, but also enhance the overall grade and consumer experience of the product.
Plastic film
Plastic film is the main component of toast bread bags, and common materials include polyethylene (PE), polypropylene (PP), and polyester (PET). These materials each have their own advantages:
Polyethylene (PE):
PE film is soft, easy to process, cost-effective, has good sealing and moisture resistance, and is very suitable for use in toast bread bags. It can effectively prevent external moisture from entering and keep the bread dry and fresh.
Polypropylene (PP):
PP film has high heat resistance and mechanical strength, making it suitable for packaging processes that require high temperature treatment. Although slightly more expensive than PE, its durability makes it the preferred choice for some high-end toast and bread packaging.
Polyester (PET):
PET film is known for its excellent transparency and glossiness, allowing consumers to directly see the appearance of bread and increasing their desire to purchase. Meanwhile, PET also has good barrier properties, which can protect bread from external pollution.
Paper
Paper plays a role in enhancing the structure, improving printing effects, and enhancing aesthetics in toast bread bags. Commonly used papers include kraft paper, white cardboard, and copperplate paper
Kraft paper:
Kraft paper has the characteristics of toughness and durability, which can increase the load-bearing capacity of packaging bags and is suitable for packaging larger or heavier toast bread.
White cardboard:
White cardboard has a smooth surface and good printing effect, suitable for packaging toast bread that requires exquisite printing, which can enhance the product's sense of grade.
Copperplate paper:
Copperplate paper has extremely high printing adaptability and high color reproduction, and is commonly used for packaging toast bread that requires high-definition patterns.
Aluminum foil
Aluminum foil is a very important layer of material in toast bread bags, with excellent barrier properties. Aluminum foil can effectively prevent the damage of light, oxygen, and moisture to food, thereby extending the shelf life of food and ensuring its freshness and taste. Adding an aluminum foil layer to a toast bread bag can significantly enhance the freshness of the packaging, keeping the bread soft and delicious for a longer period of time.
Iron wire curling design
In addition to the above materials, toast bread bags often use a wire rolled edge design. This design tightly rolls up the bag opening with iron wire, forming a tight sealing structure, effectively preventing the invasion of external air, moisture, and bacteria. The wire rolled edge bag not only extends the shelf life of toast bread, but also prevents the bread from getting damp and moldy. At the same time, its convenient access and space saving storage characteristics are also deeply loved by consumers.
