Gram hnyav, xeem txoj kev, chav hloov dua siab tshiab thiab cuam tshuam rau Gift Paper Boxes printing

Quantitative feem ntau hu ua gram qhov hnyav, hu ua qhov hnyav hauv Hong Kong thiab Taiwan, hais txog qhov hnyav ntawm daim ntawv hauv ib cheeb tsam, feem ntau qhia hauv grams ib square meter. Quantity yog qhov yooj yim tshaj plaws lub cev Performance index ntawm daim ntawv, nws qib thiab nws cov uniformity cuam tshuam rau tag nrho lub cev, mechanical, optical thiab printing zog ntawm daim ntawv.

Various performance indicators of general printing paper, such as thickness, tensile strength, bursting strength, opacity, etc., are closely related to quantification. If the basis weight of the paper is significantly lower than the standard, it will not only be prone to printing failures, but also break due to insufficient mechanical strength. On the contrary, if the basis weight is too high, pulp will be wasted in production, and the user's practical area per ton of web paper cannot be guaranteed. When the quantitative weight of a piece of paper is not uniform, inaccurate overprinting, unclear writing and inconsistent picture color and luster will occur.

Ntau units thiab kev hloov pauv

Chav tsev ntau ntawm kev ntsuas yog qhia nyob rau hauv gsm, uas yog lub thoob ntiaj teb cov chav tsev. Tab sis muaj ob qho ntxiv (feem ntau siv) rau qhov hnyav (ob qho tib si kraft thiab kraft) hauv Tebchaws Meskas: lbs / 1000 sq. ft. (LBS / 1000ft2) thiab lbs / 3000 sq. ft. Cardboard; tom kawg yog siv rau nyias nyias.

Yog hais tias koj hloov los ntawm imperial system mus rau metric system, koj yuav muab tau los ntawm tus coefficient: grams/square meter=(pounds/1000 square feet) x 4.888; grams/square meter=(phaus/3000 square feet) x 1.627

The unit we commonly use is correctly GSM (Gram Square Meter), which is g/㎡, which is calculated on a single sheet of paper.

Hloov algorithm rau phaus thiab GSM:

Phaus=Grams Inches (qhov ntev thiab qhov dav ntawm daim ntawv hloov ua lus Askiv) / 1406

Kev txiav txim siab ntawm grammage ntawm corrugated cardboard nyob rau hauv txhua txheej

In corrugated cardboard, because each layer of paper is glued together, it is difficult to know its gram weight by directly weighing a 100-square-centimeter sample like the base paper. Here, the "Packaging Zone" micro-editing recommends two methods for you:

1. Txoj kev nkag siab

Yog tias koj muaj cov qauv ntawm txhua txheej ntawm corrugated cardboard ntawm tes, maj mam tev tawm txhua txheej ntawm corrugated cardboard, hnov ​​lub thickness ntawm koj ob txhais tes, thiab siv lub qhov muag liab qab los txheeb xyuas qhov kev ntxhib los mos thiab xim ntawm daim ntawv los txiav txim lub npe specification ntawm lub puag ntawv. Txoj kev no tsuas yog rau cov neeg ua haujlwm paub txog thiab cov kws tshaj lij.

2. Baidu kuaj ntim

Feem ntau, tshwj xeeb tshaj yog rau lub hauv paus ntawv ntawm tib hom, lub thickness ntawm lub hauv paus ntawv ntawm tib gram hnyav yog tib yam. Yog li ntawd, cov ntawv txheej tuaj yeem maj mam tev tawm, thiab cov grammage tuaj yeem raug txiav txim los ntawm kev ntsuas lub thickness ntawm daim ntawv.

3. Qhov ntsuas qhov tseeb

Siv 2020CM square corrugated cardboard, tsau rau hauv dej li ib nrab ib teev, thiab maj mam tev tawm txhua txheej ntawm daim ntawv los ntawm tes. Tom qab ua tiav, nws yog qhov zoo tshaj rau khawb tawm cov kua nplaum ntawm cov kab muab tshuaj txhuam nrog rab riam. Tom qab ntawd muab cov ntaub ntawv tev tawm hauv cov av noo tas li thiab cov av noo ib puag ncig rau 48 teev kom sib npaug. Thaum kawg, qhov ntsuas qhov ntau ntawm txhua txheej ntawm daim ntawv tuaj yeem ntsuas raws li txoj kev ntsuas qhov ntsuas qhov ntsuas ntawm cov ntawv hauv paus.
