Description
Technical field
The invention belongs to convenience food packages technical field, be specifically related to a kind of can the instant food bowl cover of heating using microwave and manufacturing process thereof.
Background technology
Instant noodles, as a kind of instant food, with its instant, multiple tastes and extensively getting consumer reception, along with the quickening of people's rhythm of life, adopt the application of microwave-oven-heating food more and more extensive.At present, instant noodle bowl lid is for ensureing its flatness, sealing and humidity resistance, its internal layer all adopts aluminium foil, and the project organization containing aluminium foil layer, micro-wave oven can produce electric spark and microwave reflection with aluminium foil layer when heating, not only damage body of heater but also be difficult to cook food, therefore can not heating using microwave be applied to containing the composite of aluminium, be difficult to meet the allegro life requirement of modern, if and aluminium element Excess free enthalpy, can produce certain harm to health, if be used for heating containing the packaging for foodstuff of aluminium, security is also unwarrantable.
In prior art, also have not containing the instant food bowl cover of aluminium foil layer, as notification number: CN 201686158 U, the instant noodle bowl lid of heating using microwave " a kind of can ", it is by PET film top layer, ink layer, polyurethane glue-line, two copper ply of paper, polyurethane glue-line, PET film layer, polyurethane glue-line and inner layer of polypropylene are closely composited, although this bowl of lid does not contain aluminium and ensure that flatness with two copper ply of paper, but two copper paper cost is higher than general paper, and two copper paper belongs to art paper, and art paper smooth surface, ink absorption ability is poor, poor adhesive force, the layer of ink stamped, sometimes easily to decolour because of dry linting, art paper due to coating many, often shedding can be run into and the printing space of a whole page presents shadow phenomenon in printing process, so two copper paper is not suitable for the pattern that printing instant noodle bowl covers.Also some are had to adopt the bowl lid of paper two sides composite plastic film, as notification number: CN 201154801 Y, " a kind of instant noodle bowl lid paper ", it is made up of base paper, adhesive phase, plastic sheeting, adhesive phase is coated on the two sides of base paper, plastic sheeting through heat-sealing compound over the binder layer, this bowl of lid paper does not arrange aluminium foil layer, paper and both sides plastic sheeting seal compound tense, common combination process is adopted to be difficult to ensure that its flatness meets the requirements, when flatness is excessive, not during composite demand, when bowl lid is fitted on bowl body, difficulty is just larger.
Summary of the invention
The present invention is directed to that prior art exists containing aluminium foil layer papery instant food bowl cover can not heating using microwave, not containing the papery instant food bowl cover of aluminium foil layer be difficult to ensure the disadvantage of flatness requirement invent a kind of can the instant food bowl cover of heating using microwave and manufacturing process thereof, this bowl cover is not containing aluminium foil layer, the instant food sealed with this bowl cover can heating using microwave, bowl cover manufacturing process is when each compound working procedure, by controlling the Tension Difference between layers of material, with adhesive, layers of material is carried out compound, ensure that the finished product bowl cover paper after compound reaches flatness requirement.
