簡言之，影響復合季節的氣候變化也是環境濕度和溫度兩大指標的變化：具體來說，春夏季，特別是雨季，空氣相對濕度較大，甚至可以達到飽和，而秋冬季，空氣干燥，濕度小；在氣溫方面，夏季比冬季高得多，兩者之間的更大差值可以接近30～40℃（以南方地區為例）。
In short, the climate change that affects the composite season is also the change of two major indicators of environmental humidity and temperature: specifically, in spring and summer, especially in the rainy season, the relative humidity of the air is relatively high, or even saturated, while in autumn and winter, the air is dry and the humidity is low; In terms of temperature, the temperature in summer is much higher than that in winter, and the greater difference between the two can be close to 30-40 ℃ (take the southern region as an example).
如果不注意這些差異，在配制時可能會遇到以下問題：空氣潮濕時，膠往往不能完全固化，即不能完全干燥，殘余粘度大、嚴重，甚至在剝離復合膜時會出現拉絲現象，特別是當薄膜本身具有很強的吸濕性時，例如尼龍膜用于復合時，這種現象更為簡單；其次，潮濕的空氣會凝結在膠輥上，從而將水帶入膠盆。隨著時間的推移，膠水會逐漸變得混亂和白色，從而失去粘合效果。

If we don't pay attention to these differences, we may encounter the following problems: when the air is humid, the adhesive can't be completely cured, that is, it can't be completely dried, the residual viscosity is large and serious, and even there will be wire drawing phenomenon when stripping the composite film, especially when the film itself has strong moisture absorption, such as when nylon film is used for composite, this phenomenon is more simple; Secondly, the humid air will condense on the cots, thus bringing water into the rubber basin. As time goes on, the glue will gradually become confused and white, thus losing the bonding effect.
高溫和潮濕也使膠水難以保存。如果工作膠沒有在同一天用完，它往往會變成白色并凝聚成凝膠（果凍）凝膠。相反，當冬季寒冷時，以前未用過的工作膠在一夜之間仍會粘附到優異的透明流動性，甚至可以直接在機器上使用，而不必在新制備的工作膠中分批混合。另一方面，在冬季溫度較低時，膠水會變稠，流動性降低。當覆膜機高速運轉時，大量氣泡簡單地堆積在膠水表面和上膠網紋輥邊緣。此時，可能會有氣泡轉移，由于膠量不足，可能會影響復合牢度。
High temperature and humidity also make it difficult to keep the glue. If the work glue does not run out on the same day, it tends to turn white and coagulate into gel (jelly) gel. On the contrary, when the winter is cold, the previously unused adhesive will still adhere to the excellent transparent fluidity overnight, and can even be used directly on the machine without batch mixing in the newly prepared adhesive. On the other hand, when the temperature is low in winter, the glue will thicken and the fluidity will decrease. When the laminating machine runs at high speed, a large number of bubbles simply accumulate on the glue surface and the edge of the roller. At this point, there may be bubble transfer, due to the lack of glue, may affect the composite fastness.
同時，由于復合膜的平整度和松弛性能差，復合膜的外觀也較差。例如，膠水的流動網紋比較明顯，有時呈桔皮狀，當用于層壓時，如果印刷表面有大面積的白墨或淺色墨，則在鋁箔或鋁涂層結合時更容易形成小白點和斑點；否則，由于冬季氣溫較低，養護室的溫度與外界環境溫度相差很大。如果保溫方法不到位，熱損失率遠遠快于高溫夏季，這往往使養護室內的溫度達不到設定溫度（一般為50攝氏度）。因此，催熟效果也受到一定程度的影響。在同一成熟期，復合牢度可能低于夏季。
At the same time, the appearance of the composite film is poor due to the poor flatness and relaxation properties of the composite film. For example, the flow pattern of glue is obvious, sometimes orange peel. When it is used for lamination, if there is a large area of white ink or light color ink on the printing surface, it is easier to form small white spots and spots when the aluminum foil or aluminum coating is combined; Otherwise, due to the low temperature in winter, the temperature of the curing room is quite different from that of the external environment. If the heat preservation method is not in place, the heat loss rate is far faster than that in high temperature summer, which often makes the temperature in the maintenance room less than the set temperature (generally 50 ℃). Therefore, ripening effect is also affected to a certain extent. At the same maturity stage, the composite fastness may be lower than that in summer.
