Description
Technical field
The utility model is related to cup lid more particularly to a kind of heat-resisting cup lids of polylactic acid.
Background technology
Either refreshment can use the non-washing cup of papery or plastic cement to contain tyre beverage for general cafe, eating and drinking establishment, and
A cup lid can be covered with sealing cup mouth in cup upper edge, the liquid in cup is avoided to overflow and is convenient for carrying.Since part beverage is
Hot drink, the cup lid must be heat-resisting, and cup lid comes off in order to prevent, and cup lid must have certain structural strength and hardness, therefore, existing
Cup lid is all by systems such as the petroleum-based plastics polystyrene of the characteristics such as processability is good, heat resistance is good, mechanical strength is high, polypropylene
Into.But since polystyrene, polypropylene are not easily decomposed in natural environment, when burying through discarding or waste treatment with soil,
It will not be decomposed due to for years, CR Critical harm can be caused to environment.In addition, it is taken with the cup lid made by polystyrene
With the cup for containing hot drink in use, cup lid may be made to discharge noxious material because of hot environment, cause hot drink contaminated, so as to
It is detrimental to health.
In view of this, another cup lid is made of polylactic acid currently on the market, although polylactic acid is biodegradable material
The problem of material, discarding can be decomposed in natural environment, will not caused in environmental protection after use, using this biodegradable material of polylactic acid
Cup lid made of material, heat resistance is bad, and the easy softening transform of cup lid heat of traditional structure made of poly-lactic acid material is led
Causing the leakproofness of cup lid and cup reduces, and easily comes off, causes liquid splash in cup, to user bring it is greatly inconvenient, it is necessary to
To improving the structure of polylactic acid cup lid, the intensity and hardness of polylactic acid cup lid structure are improved.
The content of the invention
The utility model causes cup lid and cup for the easy softening transform of polylactic acid cup lid heat in the prior art
