What kind of PP sheet can be used for cheese stick packaging?

PP sheet used for cheese stick packaging need to have certain characteristics to ensure food safety, physical properties of the packaging and consumer experience.

PP plastic sheets used for cheese stick packaging boxes need to meet the following conditions:

Food safety

Food contact certification: must comply with relevant regulations and standards for food contact materials, such as FDA, European Union (EU) regulations, GB standards, etc., to ensure that the material is harmless to food safety.

Non-toxic and harmless: ensure that the material does not contain harmful chemicals to avoid migration into food.

Mechanical properties

High strength and durability: PP materials should have sufficient strength and toughness to withstand mechanical shocks during transportation, storage and daily use without breaking easily.

Excellent sealing: can effectively seal the package to prevent cheese sticks from getting damp, oxidized or contaminated during storage and transportation.

Thermal properties

Heat resistance: PP has good heat resistance and can maintain stability under heating or refrigeration conditions to avoid deformation or degradation.

Heat sealing performance: the material should have good heat sealing performance to ensure that the packaging box can achieve a good sealing effect through the heat sealing process.

Chemical stability

Anti-grease and acid-base resistance: PP materials should have good resistance to grease and acidic substances in cheese and will not be corroded or dissolved.

Anti-odor migration: Prevent the odor of packaging materials from migrating into food and affecting the taste of cheese.

Physical properties

Transparency and aesthetics: For packaging with display effects, PP sheets should have good transparency so that consumers can clearly see the cheese sticks in the package.

Barrier properties: It has certain barrier properties and can effectively prevent the entry of oxygen, water vapor and other gases, extending the shelf life of cheese sticks.

Processability

Formability: PP sheets should have good thermoforming properties and can be easily formed into the required packaging box shape during the production process.

Printing adaptability: It can perform high-quality printing to meet the display needs of brand and product information.

Environmental impact

Recyclability: PP materials should have good recyclability, meet environmental protection requirements, and reduce environmental impact.
