Whether BOPP color thermosensitive synthetic paper can be used for food packaging mainly depends on its material characteristics and whether it meets food safety standards.
First, BOPP material characteristics
BOPP (Biaxially stretched polypropylene) film has high strength, high toughness and good tear resistance, along with a high degree of optical transparency and excellent gloss, which makes it excellent in transparent packaging and display products. However, when BOPP is combined with thermal synthetic paper, its characteristics may vary due to the addition of thermal layers.
Second, the characteristics of thermal synthetic paper
Thermosensitive synthetic paper is usually composed of a substrate and a heat-sensitive material, which can be a thin film material such as BOPP. A heat-sensitive material contains a thermogenic chemical that generates images or text on paper by heat-sensing. This material is mainly used for thermal printing and is commonly found in instant printing applications such as receipts and labels.
Third, food packaging requirements
For food packaging materials, a series of strict safety standards must be met to ensure that food is not contaminated during storage and transportation, and that the packaging materials themselves do not cause harmful effects on food. According to the relevant provisions of the Food Safety Law of the People's Republic of China, packaging materials must be safe, non-toxic and cannot cause contamination to food.
Fourth, the application of BOPP color thermal synthetic paper in food packaging
1.Safety: If the thermal layer material in BOPP color thermal synthetic paper meets food safety standards, and the overall material does not release harmful substances during processing and use, then it may be used for food packaging. However, this requires rigorous security assessment and testing.
2.Applicability: Since thermal synthetic paper is mainly used for instant printing, such as receipts, labels, etc., its applicability in food packaging may be relatively limited. For foods that require long-term storage or transportation, more durable and stable packaging materials may need to be considered.
3.Compliance: Before using BOPP color thermal synthetic paper for food packaging, it must be ensured that it complies with all relevant food safety regulations and standards.
Fifth, conclusion
In summary, whether BOPP color thermal synthetic paper can be used for food packaging is not a simple yes-no question. It depends on the specific characteristics of the material, whether it meets food safety standards and the needs of the specific application scenario. Therefore, before deciding to use, it is recommended to carry out adequate safety assessment and testing, and consult the relevant professional bodies or experts.
