PLA straws use renewable plant lactic acid as raw material, which has the advantages of renewable raw materials, fully degradable and biosafety. It is a project developed on the basis of traditional polypropylene (PP) straws in recent years. The production process is simple and the production cycle is short. It adopts a one-time extrusion molding process, and with the help of the extrusion action of the screw, the heated and melted PLA particles are extruded through the die under the pressure of the die, cooled and shaped by the water tank, and then cut into different sizes of sip straws.
The biodegradable boba straws can be degraded to generate CO2 and H2O, which do not pollute the environment and can meet the needs of industrial composting. The straw extruded at high temperature has good thermal stability and good solvent resistance. The gloss, transparency and feeling can replace petroleum-based products. The physical and chemical indicators of the product can meet the requirements of local food safety regulations. Therefore, it has a wide range of applications and can basically meet the needs of most beverages on the market.
PLA straws have good moisture resistance and airtightness, stable performance at room temperature, but will automatically decompose when the temperature is higher than 45°C or under the action of oxygen enrichment and microorganisms. Special attention should be paid to the temperature during the transportation and storage of the product. Long-term high temperature will cause deformation of the PLA straw. Biodegradable boba straws are limited by the performance of raw materials, and cannot be used for hot drinks during use, but are suitable for cold drinks.
Paper straws use food-grade virgin wood pulp paper as the main raw material, and are processed by three or four layers of food-grade base paper gluing, rolling, slitting, drying and other steps. During the molding process, it is necessary to pay attention to factors such as machine speed and amount of glue, and adjust the diameter of the straw through the size of the mandrel. The entire production process of paper straws is relatively simple and easy to mass-produce.
However, the price of paper straws is high, and the use experience needs to be optimized. It is necessary to use paper and adhesives that meet food safety requirements. If it is a paper straw with a printed pattern, the food safety of the ink is also required to meet the requirements, because they all need to be in direct contact with food, and the food safety of the product must be guaranteed. At the same time, it must be suitable for many beverages on the market. Many paper straws will soften and crack when contacting beverages with high temperature or acidic beverages. These are problems that we need to pay attention to.
Starch straws are produced with wheat, rice, corn, cassava, potatoes and other natural crop starch as the main raw materials. After a lot of verification and testing, they can meet the needs of contacting different beverages and dairy products. The starch straws will not melt in use, but also are edible, causing no pollution and achieving the environmental protection. The production process of starch straws abandons the traditional production method of straws and creates a new production method.
Glass straw: Made of high borosilicate glass, the appearance of the product is clear and transparent, clean and hygienic and easy to clean. It is resistant to cold and heat, and can be used whether it is juice, milk tea or hot coffee. The upper and lower ports of the straw are polished to avoid causing scratches to the user. Whether it is the elderly or children can use it at will.
Stainless steel straws: Made of food-contact grade materials, the metal material on the surface of the stainless steel straws will not cause harm to human health. The product has beautiful appearance and can be used repeatedly, reflecting the concept of environmental protection. For reusable straws, cleaning and disinfection are the top priorities. In order to solve this problem, each pack is equipped with a special cleaning straw brush for cleaning and disinfection.
