The material of bread bags must meet the following key requirements, mainly to ensure food safety, keep the bread fresh, and facilitate storage, transportation and display. The details are as follows:
1. Must meet food contact safety standards
The material must pass national or international food grade safety certification, such as:
China: GB 4806.7 "Plastic materials and products for food contact"
USA: FDA CFR 21 certification
EU: EU 10/2011 regulations
No toxic and harmful ingredients (such as heavy metals, phthalates, etc.)
No odor, no migration into food
Reason: Prevent packaging materials from releasing harmful substances to contaminate bread and protect consumer health.
2. Good moisture-proof, oil-proof, breathable or sealing properties
Requirement: The material should have appropriate moisture-proof properties to prevent the bread from getting damp and deteriorating;
Oil-proof properties to prevent grease from penetrating and contaminating the outside;
Some products (such as baguettes and hot bread) require moderate breathability to prevent water vapor accumulation and cause softness or mold;
You can choose a sealable or perforated breathable design according to the type of bread.
Reason: Keep the bread soft and dry, and extend the shelf life;
Reduce the growth of bacteria or mold.
3. Excellent physical properties
Requirement: The material should have certain strength and flexibility, tear resistance and pressure resistance;
Suitable for heat sealing, perforating, embossing and other processing technologies;
Can be used for manual or automated packaging production lines.
Reason: Ensure that the packaging is not easily damaged during transportation and sales, and is easy to operate and display.
4. Good printability and aesthetics
Requirement: The surface of the material is suitable for printing corporate brands, food information, production dates, etc.;
High transparency or matte effect to enhance visual beauty.
Reason: Meet consumers' needs for beautiful packaging and complete information;
Enhance product competitiveness and brand image.
5. Environmental sustainability (trend requirements)
Requirements: The material should be recyclable or degradable (such as PLA, paper-plastic composite);
Reduce carbon emissions and comply with environmental regulations.
Reason: More and more countries have proposed mandatory or encouraging policies for the environmental protection of food packaging;
Catering to the trend of green consumption and enhancing brand value.
The material of the bread bag must not only be "safe", but also "applicable" and "environmentally friendly".
It must take into account preservation, protection, beauty and sustainability while ensuring food hygiene, so as to meet the multiple needs of the modern food industry and consumers.
